To realize both toughness and size reduction of a safety switch. A safety switch is a safety switch into and from which a bolt of an actuator is inserted and pulled out. The safety switch includes a casing having a shape elongated along a first direction, a metal head having a receiving space for receiving the bolt of the actuator and provided on a first end side of the casing in the first direction, a detector for detecting a first state in which the bolt is received in the receiving space, a lock mechanism, a switching device and a first attachment portion provided in the head and having a first attachment hole into which a first attachment member is inserted.

An industrial locking switch comprises multiple locking tongue entry slots formed on adjacent sides of the locking switch housing, thereby supporting receipt of the corresponding locking tongue from multiple directions of approach without the need to mechanically modify the switch's head or to reorient the switch itself. The locking switch houses locking bolt detection circuity comprising multiple series connected RFID coils configured to detect an RFID tag mounted on the locking tongue when the locking tongue is inserted into any of the entry slots.

Embodiments provide an Energy Reduction Maintenance Setting (ERMS) key that includes a data connector configured to communicatively couple to a data port of a target device. The ERMS key further includes an illumination device and an actuator mechanism having a base positional state and an actuated positional state. The ERMS key includes logic configured to, upon detecting the actuator mechanism has moved from the base positional state to the actuated positional state, generate and transmit a first data message to the target device through the data connector instructing the target device to enter a protected mode. The logic is further configured to, upon receiving a second data message from the target device over the data connector acknowledging that the target device as successfully entered the protected mode, cause the illumination device to illuminate.

A locking apparatus for a circuit breaker includes a locking pin including a main body; a rotatably or displaceably mounted definition tip; and a guide including a mating contour. In an embodiment, the locking pin is movably mounted within the guide. The definition tip is in alignment with the locking pin in a first position, such that the locking pin together, with the definition tip, is movable through the guide. Further, the definition tip cannot be moved through the guide in a second position, owing to the deflection of the rotatably and displaceably mounted definition tip of the locking pin.

A circuit breaker includes an accessory pocket, an accessory cover and a locking device to lock the circuit breaker such that an unauthorized switching of the circuit breaker from OFF to ON or from ON to OFF states is prevented. The locking device includes a first subassembly including a pocket housing. The first subassembly is configured to be installed in the accessory pocket. The locking device further includes a second subassembly including a cylinder lock. The second subassembly is configured to be mounted to the accessory cover. The first subassembly and the second subassembly are configured to self align upon final assembly of the circuit breaker to perform a locking function of the circuit breaker. In this way, the locking device prevents circumvention of a locking feature and selectively provides an ability to lock in an ON state of the circuit breaker.

A simple kit of parts is provided that can be used to replace a few easily removed elements of a lockable push button actuator of a mechanical locking mechanism to convert the push button actuator to a lockable actuator for controlling a switch that can serve as a component of an electrical locking system. Other aspects of the invention relate to a method of making the mechanical to electrical conversion, and to a lockable actuator for operating an electrical switch connected to the actuator.

A mechanical interlock for a switch gear switch. The mechanical interlock includes a base and a slider. The slider is moveable relative to the base between a first position and a second position. The mechanical interlock is configured to lock the position of the switch when the slider is in the second position.

Embodiments provide an Energy Reduction Maintenance Setting (ERMS) key that includes a data connector configured to communicatively couple to a data port of a target device. The ERMS key further includes an illumination device and an actuator mechanism having a base positional state and an actuated positional state. The ERMS key includes logic configured to, upon detecting the actuator mechanism has moved from the base positional state to the actuated positional state, generate and transmit a first data message to the target device through the data connector instructing the target device to enter a protected mode. The logic is further configured to, upon receiving a second data message from the target device over the data connector acknowledging that the target device has successfully entered the protected mode, cause the illumination device to illuminate.
