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.

An operating modes selector is for an earthing switch that includes power contacts and a motor for moving the power contacts. The selector includes a plurality of positions corresponding respectively to various operating modes of the earthing switch, and includes cams whose positions are defined by the selector position. The selector contains a first cam which pulls a first locking organ designed to mechanically block the motor of the earthing switch when the selector is in a position corresponding to a locked closed mode wherein the earthing switch is closed.

A wall switch lockout device for selectively limiting access to a wall switch relative to which the wall switch lockout device is mounted. The wall switch lockout device includes a mountable base having a switch opening extending therethrough for receiving the wall switch, a cover positionable and securable over a front face of the mountable base for selectively covering and limiting access to the switch opening, and one or more inserts received in the mountable base and slidable relative thereto. The wall switch lockout device further has a pair of mounting openings for mounting the mountable base and at least one of the pair of mounting openings is on the one or more inserts such that, when the one or more inserts are slid relative to the mountable base, a hole-to-hole distance between the pair of mounting openings is variably adjusted.

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 mounting frame may be configured as a self-adjusting mounting frame that biases itself against a surface of structure. The mounting frame may be a component, for example, of a remote control device or a faceplate assembly. The mounting frame may be configured to bias a rear surface of the mounting frame against the surface of a structure. The mounting frame may include biasing members. Each biasing member may include an attachment portion and a pair of resilient spring arms that suspend the attachment portion relative to a perimeter wall of the mounting frame such that the attachment portion is spaced further from the rear surface of the mounting frame than locations where the spring arms extend from the mounting frame. The rear surface of the mounting frame may be defined by the perimeter wall.

An electric vehicle is supplied with power from a power supply via a cable suspended from an anchor. The anchor is attached to a mount on the vehicle and detachable from the mount by tension in the first portion of the cable between the anchor and the power supply. A second portion of the cable between the anchor and the vehicle remains slack in the attached position of the anchor, and extends on detachment of the anchor to relieve tension in the first portion of the cable. A disconnection switch is operable by detachment of the anchor to interrupt the power supply from the cable to the vehicle.

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 external switch coupler includes: a guide tube having a first end and a second end, the first end configured to be attached to a door of a compartment in substantial alignment with both a hole in the door and a switch coupler within the compartment, and the second end configured to be disposed within an interior of the compartment and separated from the switch coupler by a gap when the door is closed; a coupling shaft configured to be operably placed within the guide tube, the coupling shaft having an electrically insulative member disposed between an coupler side adapter and a switch side adapter, and a length equal to or greater than a distance between the switch coupler and the hole in the door when the door is closed.

A non-mechanical-interfacing electronic switch or a mechanical-interfacing electronic switch are controlled to modulate between an active state and an inactive state based on electronic action. The switch includes an aperture defining an opening in a housing, and the opening defines an insertion path. A transmitter transmits a signal to a receiver along a signal path. To control the non-mechanical-interfacing electronic switch, a mechanical lockout device having a protrusion is inserted through the opening of the aperture along the insertion path. To control the mechanical-interfacing electronic switch, a mechanical control part have a protrusion is moveable to interrupt the signal. Methods of locking the non-mechanical-interfacing electronic switch with the mechanical lockout device as well as methods of locking the mechanical control part of the mechanical interfacing electronic switch with the mechanical lockout device are also provided.
