Patent ID: 7342189

Claim:
Actuating device ( 1 ) for an electrical switch device comprising: a body ( 10 ) upon which is mounted a hand lever ( 2 ) that rotates about a main axis (A), cooperating with a transmission shaft ( 3 ) able to control the opening or the closing of electrical contacts of the electrical switch device, elastic linking means between the hand lever ( 2 ) and the transmission shaft ( 3 ), means ( 7 ) for locking the rotation of the hand lever ( 2 ) with respect to the body ( 10 ), used when an angular divergence between the hand lever ( 2 ) and the transmission shaft ( 3 ) exceeds a specified threshold, wherein the locking means comprise a locking device ( 7 , 7 a , 7 b ) that is rotational about an axis parallel with the main axis (A), and in that the locking device is made to pivot by the hand lever ( 2 ), in a temporary manner, each time that the angular divergence between the hand lever ( 2 ) and the transmission shaft ( 3 ) exceeds a specified threshold.
