Abstract
Pulse push-button which includes a tubular pusher member guided in translation through a cylindrical body and acting on electrical contacts. The pusher member is fitted with a cam that operates in conjunction with the active section, for example an elbowed tip, of a hairpin-shaped spring. The cam has at least one reversing point and the adjacent wall of the pusher is also fitted with a step member that allows the active section of the spring to strike the bottom of the step when the elbow passes over the step.
