Japanese Patent JPH0355930
Kind Code:
B2
Abstract:
At least one actuating or cut-off spring is provided which is compressed in the cut-on or closed position of the switch and is coupled to an actuating linkage or rod leading to movable contacts of the switch. An arrangement is provided to variably modify the force exerted by the actuating spring on the actuating linkage in relation to the stroke. This arrangement consists of a force transmission device arranged between the actuating spring and the actuating linkage. The force transmission device permits taking into account the type of switching stroke to be executed and optimally adapting the force pattern during a switch cut-off stroke thereto. The variation of the force pattern during the switch closing or cut-on stroke is not symmetrical to that of the switch opening or cut-off stroke. The force transmission characteristics of the force transmission device are different according to the requirements of the switching stroke to be executed. The force transmission device is designed to suddenly reduce the force acting on the actuating linkage during a switch opening or cut-off stroke.
