When an initial position of an enabling switch is given as a first position (301), a position of the enabling switch in which a movable member is most pressed is given as a third position (303), and a rising start position of a maximum rise of a load is given as a second position (302), the rising start position being between the first position (301) and the third position (303), a minor peak (341) of the load appears between the first position (301) and the second position (302). An ON switching position (311) is between a falling start position (323) of the minor peak (341) and the second position (302). A maximum load during the minor peak (341) is greater than or equal to the load in the ON switching position (311) and less than or equal to the load in an OFF switching position (312).

A safety device cabinet includes an equipment cabinet, a safety switch having an integrated light, a switch logic circuit and a battery back-up. The safety device cabinet includes an equipment cabinet and an access door. The access door includes a window and an edge light emitting device. The window is etched with a message containing a description of the equipment stored in the equipment cabinet. The safety switch with an integrated light includes a push momentary switch, a light bezel and a bezel light source. An inner perimeter of the outer shell is sized to receive a push button of the push momentary switch. The light bezel preferably includes an opening to receive a light emitting portion of the light source. The switch logic circuit preferably includes a AC to DC converter, a microprocessor, a software program and a monitoring device.

Provided is an electric switch, including a casing, an actuator, a movable contact frame, a snap-action resilient member, a lock mechanism, a signal switch and a contact switch. The actuator is capable of reciprocating along a first direction. The movable contact frame is provided with a retaining portion. The snap-action resilient member is arranged in the movable contact frame and is compressed by the actuator when the actuator moves. The lock mechanism includes two lock members which are capable of reciprocating in the mounting cavity along a second direction with the movement of the actuator, so as to lock or unlock the retaining portion. A brush of the electric switch is arranged on the movable contact frame. A movable contact of the contact switch is arranged on the movable contact frame.

A switch assembly including a socket, a top cap, and an intermediate cart located in the socket. The intermediate cart is slidable with the socket. The top cap is in a spherical or pivot engagement with the intermediate cart. An activation force of the sliding movement is lower than an activation force of the spherical or pivot movement.

A device is provided for controlling the ignition of gas burners of a domestic cooking appliance. The device includes an electric switch with an insulating casing that carries a pair of fixed electric contacts. A movable body carries a movable electric contact that cooperates with the fixed electric contacts. The movable body is displaceable with respect to the casing between an open position and a closed position. An elastic element elastically pushes movable body toward the open position. A flexible cable has a first end that is anchored to the movable body and a second end that is anchored to a fixed support. A plurality of actuating members is associated with respective gas taps and have movable elements that cooperate with respective sections of the flexible cable. Each actuating member can bend a respective portion of the flexible cable into corrugated shape during the opening of the respective gas tap.
