Abstract: Double-pass pushbutton, able to act successively on one or both independent microswitches (M1), (M2), where the body shell and the pushbutton have a leaktight and flexible cap mounted between them, which hermetically seals the joint without interfering with the guided axial movement of the pushbutton, with respect to the body to be activated, or stopping the operator's action; it has two contact stops at different heights, for their successive contact with the relative rnicroswitches when moved linearly; and there are means between the body shell and the pushbutton for the successive positioning of the pushbutton. The pushbutton is especially useful in control pushbutton panels.
