A spring for an electric switch comprises a base portion, a contact section, and a return spring section. The base portion forms a proximal end of the spring. The contact section extends from the base portion to a distal end of the spring opposite the proximal end. The contact section has a contact member. The return spring section extends from the base portion alongside the contact section.

A spring for an electrical switch comprises a contact arm and a base from which the contact arm extends. The contact arm has a contact member. The base has a terminal and an extension. The extension extends from the contact arm to the terminal and away from a remaining base.

The invention describes a control and signaling device which comprises the following: a cylindrical main body with two open ends, an operating element which is designed for insertion into one of the open ends of the main body and has a switching part that is movable relative to the main body, and a multipartite insert element which is designed for insertion into the main body for bridging at least one portion of a switching path from the switching part to a contact element arranged at the other of the open ends and has an elastic element which elastically supports a portion , provided for operating the contact element, of the insert element in such a way that a pressure force of the insert element onto the contact element is limited to a prespecified force range.

A contact press-on assembly for a switching contact piece of an electrical switching unit has a first stop and a second stop. A spring element extends between the two stops, wherein the first stop can move relative to the second stop. The second stop provides a counterbearing for the first stop, wherein a rotary bearing for the spring element can move together with the first stop.
