Apparatuses and methods for activating a switch are provided. The switch is supported by one of a bracket and a panel and includes a switch body and a switch plunger that is moveably coupled to the switch body to activate and deactivate the switch. In one example, the apparatus includes a clamp body that is configured to be removably coupled to the one of the bracket and the panel and that has an opening formed therethrough. The apparatus further includes a rod portion having a first end portion that has a surface that includes a first concave surface. The rod portion is configured to be advanced through the opening. The surface interfaces with the switch plunger and moves the switch plunger to activate the switch when the clamp body is coupled to the one of the bracket and the panel and when the rod portion is advanced through the opening.

An engageable lockout and tagout device for aircraft pushbutton switches prevents attempts to electrically engage a corresponding control panel circuit of a system under service. The lockout and tagout device is configured to lock different pushbutton switch types present in a flight deck, including Korry switches, thereby preventing operators from actuating switches and alerting them that the switches have been disengaged.

An apparatus includes: a shaft rotatable to a plurality of predetermined positions to change a state of an electric switching device; a motor rotating the shaft via a transmission mechanism when the apparatus operates in an electric operating mode; a braking mechanism configured to brake the motor in response to the shaft rotated to each position when operating in the electric operating mode; a disc coupled to, and rotatable with the shaft, and comprising a plurality of blocking parts and slots therebetween; and a manual lever comprising a rotatable part and a projecting part arranged at an end thereto, wherein in an apparatus manual operating mode, the projecting part is rotatable into the disc via one of the slots when the shaft is located at one of the positions, and slides out from the disc via another slot when the shaft is rotated to another one of the positions.

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.

An engageable lockout and tagout device for aircraft pushbutton switches prevents attempts to electrically engage a corresponding control panel circuit of a system under service. The lockout and tagout device is configured to lock different pushbutton switch types present in a flight deck, including Korry switches, thereby preventing operators from actuating switches and alerting them that the switches have been disengaged.

A method of applying a switch locking device to a wall switch to prevent actuation of the wall switch. The wall switch has an actuator member extending through a toggle frame in a switch plate. With the switch in the desired on or off position, the snap-on locking device will be placed in the gap between the actuator member and the toggle frame. Operation of the switch is prevented by the arm of body that goes between the actuator member and the toggle frame surface.

An appliance includes a position switch retention device for use with an appliance includes a body defining a generally cylindrical profile extending through a first portion thereof along an axis and having a first radius. The body further defines a pin-receiving channel open on at least a first end thereof and positioned within the generally cylindrical profile. The device further includes a first tab extending from a side of the body. The tab defines a ramp and an edge with the ramp extending away from the first end of the body to the edge. A cap extends outwardly from a second end of the body opposite the first end. The cap is spaced apart from the edge of the tab at a first distance and has a second radius greater than the first radius.

A disabler cover plate includes a generally flat longitudinal surface, an upper hook extending approximately 90° from a top of an underside of the flat longitudinal surface, a lower hook extending approximately 90° from a bottom of the underside of the flat longitudinal surface, and a bump out on the underside of the flat longitudinal surface, the bump out positioned to depress and maintain pressure on a button on a face of a PBS-3 fixture.

An apparatus and method for a safety interlock door switch tool are disclosed. An example embodiment includes: support posts having a top end and a bottom end; base elements coupled to the bottom end of the support posts, an attachment mechanism being coupled to the base elements; a grip element coupled to the top end of the support posts; and a plurality of switch depression surfaces formed between the support posts, each of the plurality of switch depression surfaces being configured to engage and activate a particular type of safety interlock door switch.

Systems and methods for using light switches to control lighting and other functions are disclosed. Each switch may be a manual switch that is mounted to a wall. A biasing device may be positioned proximate each switch. When a user moves the switch out of a first position and into a second position or toward a second position, the delivery of household power to one or more light units may be interrupted. However, when the user releases the switch, the biasing device may provide an immediate automatic return of the manual switch to the first position. The resulting short interruption in household power may be used as a signal for controlling operation of the one or more light units and/or other electronic devices installed at one or more lighting sites corresponding to the switch.
