A safety switch (1) having an input/output structure and means for generating a switching signal. Depending on the switching signal, the operation of the system can be released. The input/output structure forms means of connection for connecting a start button (5). By manually actuating the start button (5), an acknowledgment signal for releasing the system is generated. The means of connection are detected automatically in the safety switch (1).

A switch that is designed for use as an emergency shut off for heating, air conditioning (AC) systems or appliances is provided, but is certainly not limited to these specific applications and has applications in many other fields. The switch is configured with one or more indicators (visual and/or audible) configured to indicate when the switch has been manually turned off, even though power to the switch is still active. In this manner when the switch has been accidentally or inadvertently turned off by an unsuspecting user, they will be notified that the connected appliance (e.g. heating or AC system) has also been turned off.

A control station for electrical installation comprises a protection box (2) having a side wall (3) with a front face (4) defining a development plane (), a plurality of controls (5, 9, 20) anchored to the protection box (2), at least one of the controls being a mushroom emergency push button (9), movable electrical contacts associated with respective controls (5, 9, 20) to be connected to one or more circuits of the electrical installation for the opening/closing thereof. Each control (5, 9, 20) is associated with one or more contact units (22) having movable electrical contacts arranged in the protection box (2) The emergency push button (9) is housed in a seat (8) formed on a side face (7) of the side wall (3) perpendicular to the development plane () and is anchored to one or more contact units (22) removably housed in the protection box (2).

An actuator for switching a switching unit includes a mechanical display having a window and a display surface visible through said window, where the display surface is positioned at a guiding projection that is subjected to a force from an elastic element.

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.

An emergency off-switch for triggering an emergency switch-off function has an actuator and two electrical contact points that can be disconnected from one another by the actuator. The emergency off-switch has an active operating state in which the emergency switch-off function can be triggered by moving the actuator, and a passive operating state in which the emergency off-switch is functionless. The emergency off-switch further has a visualization unit having at least a first and a second display state. The emergency off-switch is visually highlighted in the first display state, and the emergency off-switch is neutrally represented in the second display state. The visualization unit adopts the first display state in the active operating state and adopts the second display state in the passive operating state. The emergency off-switch also has a monitoring unit which monitors whether the visualization unit is in the first or in the second display state.

A safety switch is disclosed herein. The safety switch may comprise: a housing, wherein the housing comprises a mating cam; a face plate, wherein the face plate is coupled to the housing; and a subassembly coupled to the face plate, wherein the subassembly comprises: a base, wherein the base comprises a slot; a cam, wherein the cam is positioned within the base; a pushbutton, wherein the pushbutton comprises a hole; and a pin positioned through the hole of the pushbutton and the slot of the base; wherein the cam, the base, and the pushbutton are mated together with the pin; wherein the subassembly is not rotatable due to the pin.

A modular structure for safety switches for controlling access for machines and industrial plants comprises a casing (2) housing switching means for controlling one or more circuits of the machine or plant, drive means adapted to interact with the switching means upon the opening/closing of the access, an auxiliary module (3-3.sup.v) housing at least one control (4.sup.i-4.sup.v) adapted to be manually operated to operate on the switching means and/or the drive means and comprising a box hollow body (5) having at least one opening (6) for inserting the control (4.sup.i-4.sup.v) provided with first means for removably connecting the control (4.sup.i-4.sup.v), the latter being selected within a series of controls (4.sup.i-4.sup.v) having functions different from each other and each provided with a fastening rod (7.sup.i-7.sup.v) adapted to be inserted in the opening (6) of the box body (5) and provided with second connecting means complementary to the first connecting means.

A safety-switch device for mounting on a movable device. An impact surface is mounted on or assembled in a bracket. The bracket, impact surface, and a mounting surface of the movable device form a protective enclosure around the switch. The switch is a switch strip or a switch mat. The impact surface is a separate, movable, rigid or stiff component that serves as an actuator for the switch and is provided as a component that is easily replaceable. A trigger mechanism is provided between the impact surface and the switch. When the impact surface moves from its resting position to its actuation position, the trigger mechanism trips the switch.
