A spring-operated plug terminal is disclosed. The spring-operated plug terminal includes a U- or &#x3a9;-shaped spring, which has two separate spring arms and thus two spring ends, and a rectangular terminal frame, which has a square cutout and a clamping piece which is angled away from the plane of the terminal frame. One fixed end of the spring is arranged in a fixed position in the cutout and the two ends of the spring arms, together with the clamping piece of the terminal frame, form a clamping zone for two conductor cores and/or flat plug to be connected. Each spring end includes a central, straight first section, in the form of a clamping edge, for making inter-engaging contact with a conductor core. Further, each spring end includes an edge-side, curved second section which forms a clamping surface. The clamping surface protrudes beyond the clamping edge in the direction of termination, so that contact can be made with a flat plug simply by applying pressure.

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.
