Malfunction or failure of mechanical, electrical, and electro-mechanical equipment, for example, equipment used in manufacturing operations, is often preceded by an increase in the operating temperature of at least some portion of the equipment. A temperature-sensitive, active material-containing actuator is pre-selected to operate at a pre-determined temperature indicative of impending equipment failure and placed in thermal contact with the equipment. If the equipment achieves the pre-selected temperature the actuator signals this by closing an externally-powered circuit to enable or provide a suitable alarm signal. Additionally, the actuator may close a second circuit connected to a machine controller to alert the machine controller to take some pre-programmed action. Selected actuators are based on shape memory alloys (SMA) adapted to operate over a temperature range sufficient to encompass the expected range of pre-determined temperatures.

The invention relates to a vehicle horn operating device comprising: a steering wheel skeleton structure, a support for a portion of an electric horn circuit comprising a first electrical contact point, an operating component comprising a second contact point, the operating component being able to move between a rest position and a depressed position; in the rest position, the second contact point is kept in contact with the first contact point by a spring element, the first contact point forming a first end stop for the operating component, wherein the device comprises—operating-component retaining elements arranged in such a way as to form a second end stop in the event of loading that causes the operating component to move beyond the first end stop.

A switch device structure includes an assembly of a main body and an operation body. An electrical connection module and an elastic unit are mounted on the main body. The contact arm of the electrical connection module has a first member and/or a second member with variable arrangement position. According to the position or motion of the operation body, the elastic unit provides an elastic force to push the contact arm of the electrical connection module into a contacting circuit closed state or make the elastic unit separate from the contact arm to form a circuit open state. The arrangement form of the first member and/or the second member of the contact arm of the electrical connection module is variable in accordance with the specification of the switch to achieve NO mode and NC mode.

An electrical switch including: a switch housing; a switch circuit disposed within the switch housing; said switch circuit including a movable contact member mounted on a contact lever and a stationary contact member; the contact lever being configured for operable-interaction with an actuator, said actuator being configured for movement along an actuator movement axis relative to the contact lever between at least one of an OFF position whereby the contact lever is configured for arrangement in to the first configuration whereby the switch circuit is opened, and, an ON position in which the contact lever is configured for arrangement in to the second configuration whereby the switch circuit is closed; a biasing element configured for biasing the contact lever towards the second configuration; so that the switch circuit is closed when the actuator is moved relative to the contact lever in to the ON positions, said biasing element including a first end attached to a first attachment point in connection with a portion of the contact lever and a second end attached to a second attachment point in connection with the switch housing; and an attachment member configured for attachment with the contact lever whereby when attached to the contact lever, said attachment member is configured for operation as the first attachment point in connection with the portion of the contact lever.

A closing edge safety device that triggers a safety response upon contact with an obstacle. The body of the safety device is an elastically deformable profile element that encloses a switch chamber containing a switching strip that carries an electrical current. A prechamber with a switching nub is placed at the leading edge of the safety device, in front of the switch chamber. When an external force is applied to the leading edge of the safety device, the switching nub transmits the force to the switch chamber, which also deforms, causing an interruption in the electrical current on the switching strip, thereby triggering the desired safety response of the closing edge safety device. The closing edge safety device provides improved response to large-area as well as small-area contact with an obstacle and is also suitable for use as a limit switch.

A member has a first recess, a second recess, and a depression. The depression accommodates a movable member and a contact member. Positioned on a bottom surface of the first recess is a first fixture contact, whereas positioned on a bottom surface of the second recess is a second fixture contact. When a pressure receiving section of the movable member is pressed toward a bottom surface of the depression, the movable member is elastically deformed to separate a movable joint from the contact member. When the pressure receiving section is further pressed toward the bottom surface of the depression, the movable member is elastically deformed to separate the first movable contact from the first fixture contact and to separate the second movable contact from the second fixture contact.

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.

A terminal stand is provided. The terminal stand includes a base body, a movable part, a metal elastic part, a first signal element and a second signal element. One end of the metal elastic member includes two first abutments. The first signal element is disposed in a second receiving slot. One end of the first signal element includes a first contact portion and a second abutment. The second signal element is disposed in the second receiving slot. One end of the second signal element includes a second contact portion. The second contact portion contacts with the first contact portion and makes a signal circuit. When the movable member is pressed, the movable member drives the two first abutments to move, and the abutment drives the second abutment to move, with the first contact portion leaving the second contact portion, and the signal circuit is in an off-state state.

A non-electrical device (40) includes first and second half-housings which are produced in a plastic material, are joined fixedly to one another, define an axis along which a passage for an electrical conductor passes through the first and second half-housings, and delimit between them an internal volume, which is separated from the passage and which surrounds the passage all around the axis. The first half-housing incorporates, by moulding, mechanical reinforcing elements which extend substantially parallel to the axis in the internal volume until they are in contact with the second half-housing.
