Abstract

An operating element is used on a pushbutton switch system. It enters into the case which holds fixed contacts. The fixed contacts may be connected together by a spring loaded bridge contact. A stepped spring (27) is provided between the operating element (22) and the opposite wall of the case (10). One part (28) of the spring is soft, and the other (29) is hard. The bridge contact (30) is held between the two parts of the spring (27), and depression of the button compresses the spring parts so as to push the bridge contact down onto the fixed contact.
