Abstract
A device for manually controlling a thermal relay associated with a contactor and housed, together with the contactor, in a case having stop and reset push-buttons, comprises levers mounted for rotation in a support fixed to the front of the box of the thermal relay. Each of the push-buttons engages a respective lever so that the latter is applied on a stop pusher or a reset pusher of the thermal relay. A combined stop and reset operation from the actuation of the stop push button alone is possible because the stop lever bears on the reset lever.
