NSN SM3-20DC2

A switch that is externally actuated by a device such as a push rod or button, which requires pushing for each actuation. The action may be momentary, with mechanical return. It consists of a body,switch and a push button. The item may include provisions for mounting indicating lamps or light emitting diodes in the actuator. Includes items consisting of individually separable switches that are physically interlocked, that have a common actuator, or are electrically connected. Excludes: light-switch; light-switch assembly; switch,beam selecting,headlight; switch,foot; switch,interlock; switch,pressure; switch,push-pull; switch,sensitive and switch assembly. For devices which start, stop, reverse, select and/or regulate the speed of a motor, see starter,motor and controller,motor.
