SWITCH
The problem to be addressed is to provide a highly safe and compact switch that is adapted to improvements in portability, weight reduction and size reduction of machines, or the like. An operating part has a button covering the upper part of a cylindrical housing that receives a downward pushing operation and a rotational operation. A contact unit part has contacts which open by being coupled to the downward pushing operation of the button. A twisting coil spring is disposed on the interior of the button, one end being joined to the housing, and the other end being joined to the button. A latch part disposed to the interior of the twisting coil spring, has a plunger coil spring that expands and contracts in a direction perpendicular to the direction of the downward pushing operation, and when a downward pushing operation is performed on the button, causes a sliding rod to slide along an inner wall of the housing while being displaced in the direction of the downward pushing operation.
Switch device structure
A switch device structure provides an ensuring system to improve the shortcoming of the conventional switch device. The switch device structure includes a main body and an operation button assembled with the main body. The main body defines a chamber in which a base seat is assembled. An operation body and a wire connection module are disposed on the base seat. The base seat is formed with a cavity in which an elastic unit is mounted. The elastic unit includes a fixed section and a free section. In response to the move of the operation body and with the fixed section serving as a fulcrum, the free section of the elastic unit can push a second contact of the wire connection module into contact with a first contact to close the circuit or away from the first contact to open the circuit.
Heat destructive disconnecting switch
A heat destructive disconnecting switch comprises a first conductive member, a second conductive member, a movable conductive member, an overheating destructive member, an operating component, and a second elastic member. The movable conductive member conducts electricity to the first conductive member and the second conductive member. The overheating destructive member is formed as an integral body on a limiting member, and a first elastic member is compressed to between a contact member and the overheating destructive member, thereby providing the first elastic member with a first elastic force. The second elastic member is provided with a second elastic force. When the overheating destructive member is destructed due to overheating, the first elastic force is smaller than the second elastic force, causing the movable conductive member to disconnect the first conductive member from the second conductive member to achieve a protective effect from overheating.
Emergency stop device
The invention relates to an emergency stop device, comprising: an electric module suited to being soldered onto a printed circuit board (PCB), comprising a body, at least two fixed contacts arranged in the body and at least one contact actuator bearing a moveable contact able to connect said fixed contacts electrically, an actuating module suited to being mechanically coupled to the electric module and to being mounted on a panel (P), the actuating module comprising a body and an actuator moveable with respect to the body, the body comprising a so-called rear part able to extend through the panel (P) on a side opposite to the actuator and to receive the electric module, the actuating module being able to be actuated by an operator between the following positions: a rest position in which the moveable contact ensures an electrical connection between the fixed contacts, and an activated position in which the actuator exerts a depression force on the contact actuator so as to break the electrical connection between the fixed contacts.
Said device comprises a locking system configured to secure in a reversible manner the mechanical coupling of the electric module to the actuating module.
Heat destructive disconnecting switch
A heat destructive disconnecting switch, comprises a first conductive member, a second conductive member, a movable conductive member, an overheating destructive member, an operating component, and a second elastic member. The movable conductive member conducts electricity to the first conductive member and the second conductive member. A first elastic member and the second elastic member act on an operating member. The first elastic member is compressed and provided with a first elastic force, and the second elastic member is provided with a second elastic force. When the overheating destructive member is destructed due to overheating, the first elastic force is diminished or vanishes, causing the second elastic force to be larger than the first elastic force. Consequently, the movable conductive member disconnects the current conducting state between the first conductive member and the second conductive member, thereby achieving a protective effect from overheating.
Overheating destructive switch
An overheating destructive switch, comprising: a first conductive element, a second conductive element, a movable conductive element, an overheating destructive element, an operating component, and a second elastic element. The movable conductive element connects the first conductive element and the second conductive element. A first elastic element and the second elastic element act on an operating element. The first elastic element is compressed and has a first elastic force, and the second elastic element has a second elastic force. The first elastic force is greater than the second elastic force under in a normal state. When the overheating destructive element is destroyed due to overheating, the first elastic force is reduced or lost, such that the second elastic force becomes greater than the first elastic force. The movable conductive element is consequently disconnected from the first conductive element and the second conductive element, thus achieving protection against overheating.
SWITCHING ASSEMBLY WITH SECURE ATTACHMENT SOLUTION FOR EMERGENCY STOP DEVICE
A switching assembly intended to be joined onto a control assembly provided with an actuation member, the switching assembly comprising a body, an electrical circuit comprising two fixed contacts, the electrical circuit being able to be controlled both by a control switch of a normally-closed type and by a monitoring switch of a normally-open type, linked in series with the control switch. The monitoring switch makes it possible to monitor the correct secure attachment of the switching assembly onto the control assembly by keeping the electrical circuit open as long as the control assembly is mechanically disconnected from the switching assembly.
Switching Mechanism for an Outdoor Robotic Tool
An outdoor robotic tool (100) comprising a switching assembly (104) comprising a carry handle (106) and a stop button (108) is disclosed. The carry handle (106) and stop button (108) are connected such that the raising of the carry handle (106) results in the stop button (108) being activated and vice versa. The activation of the stop button (108) results in the outdoor robotic tool (100) being rendered inoperable in some way. A lift-indication mechanism (126) may be present, which renders the outdoor robotic tool (100) inoperable if it is lifted. Either or both of the switching assembly (104) and lift-indication mechanism (126) may be present on the outdoor robotic tool (100).
Fastening device for electric control and/or indicator member
A fastening device for an electric control and/or indicator member, which includes a base, a fastening clamp fitted pivotably on the base about a first axis, the clamp including at least one branch having a free end designed to form at least a first bearing point against a wall, an element hinged about a second axis and interacting with the clamp to cause it to pivot about the first axis, a clamping screw for controlling the pivoting of the clamp, the clamp being configured in such a way that a first plane including the first axis and the second axis and a second plane including the first axis and the first bearing point form an angle of between 110 and 160.
Switch with illumination surface illuminated with different states of illumination
A switch is disclosed. In some examples, a switch includes a generally cylindrical housing; one or more sets of contact points enclosed by the housing; an indicator module, such as a multi-color LED illuminator, also enclosed by the housing; and a pushbutton actuator disposed to operate the contact points. The housing includes a display section spanning substantially the entire circumference of the housing such that the indication made by the indicator module is visible from all radial directions. When the pushbutton actuator is pressed, some of the contact points open to cut off power from hazards, while others are reconfigured to change the state of the indicator module to indicate the changed status of the switch. Multiple switches can be interfaced with each other, such as by serial connection, to facilitate multi-switch safety environment. Modular cables can be used to conveniently establish the interface.
