Abstract

The mechanism has a tension lever (3) between the operating knee lever (16) and the contact lever (1). The operating knee lever (16) co-operates with a ratchet lever (10), so that the contact lever (1) is held in the OFF position for the switch. The ratchet lever (10) is released by the amplification of the operating knee lever movement in the switch operating direction obtained due to the spring tension between the spring lever (3) and the contact lever (1). Pref. the spring lever (3), the contact lever (1) are mounted on the same axis (4) and the ratchet lever (10) is mounted on the same axis (8) as the operating knee lever (16).
