ABSTRACT:
A device for extending the actuators of electric switchgear has an extension element which is inserted between a collar and the pushbutton of the equipment. At the end facing away from the collar, the extension element ends in C-shaped, elastically resilient arms which are fastened to the equipment by means of a snap-in connection and between which the push-button is contained. The resilient mounting of the extension element serves both for holding the element to the equipment and for restoring it after actuation. The device can be used for command equipment as well as for reset buttons such as the reset button in overload relays.
