Either the pushbutton body or the pipe has at least one step on its upper surface remote from the contacts to provide a plurality of stepped strokes of depressed movement of the pushbutton body with respect to the pipe for selective actuation of the contacts. The resilient structure may be a coil spring or a resilient leaf spring.
