Abstract
An actuating device for attachment to a toggle actuated low-voltage circuit breaker having an insulating housing has a housing and a guide mechanism supported therein including a fork-shaped lever which can be turned and which transforms the rotary motion into the rectilinear motion needed to actuating the toggle lever. A slider, movably guided radial to the axis of rotation by the fork arms of the lever, has a circular cylindrical opening which receives a substantially spherical head piece. The head piece contains an opening for receiving the end of the toggle lever. The housing of the actuating device contains a slideway which serves as a guide surface for the head piece. An operating handle can be placed on a shaft end of the fork-shaped lever.
