Control mechanism, a piece tilting and for elastic return means, for the electrical apparatus has two stable positions and electrical apparatus comprising such a mechanism

摘要

A push rod (3) which can move in a reciprocating manner and is pressed to the lower end whenever it is operated supports a finger (4) which is connected to a cam profile (7) which is arranged in a rocker (5) which is coupled to an electrical contact device (6) in two stable positions. A telescopic element (16), which is provided with a compression spring (9), is supported at one end (at 30) in the push rod (3) and at the other end (at 27) in the rocker (5) in such a manner that, in each quiescent position, the finger (4) is arranged opposite one or the other of the two control switch positions (10, 11) which admits the cam profile (7).
