The invention relates to an overload safety device (1) for protecting electrical and/or electronic components from operating currents (lb) which are above a threshold operating current. In order to ensure that the overload safety device (1) prevents operating currents (lb) which are above the threshold operating current in a safe, rapid manner which is substantially independent of external factors, there is provision according to the invention for a switching device (6) of the overload safety device (1) to be able to be actuated by operating currents (lb) which are above the threshold operating current and to be constructed so as to be able to be moved from an operating state (B) into a protection state (S) and for the overload safety device (1) to be constructed with a retention device (11) which has at least one retention magnet (12, 13) which secures the operating state (B).

The invention relates to a bistable electrical switch, comprising a spring (101) which is configured in the form of a bistable elastic spring and which supports contact elements (114, 116) on the support strip (104) of the spring; and at least one driving element consisting of shape memory material per control state, for driving the spring. The spring has a leaf (110) which is permanently clamped at one end (102) and which is subjected to a compressive strain in the direction of its longitudinal extension. Buckling causes the leaf to yield to one side, into one of two stable terminal states. The areas of the spring adopt different lateral positions in the stable terminal positions. The driving elements (118, 119) act on the free end of the leaf and cause the leaf to switch to the second stable terminal state as a result of the inclination of the free end (104).

The invention relates to a switch contact subassembly (1) having a switch contact bridge (2) and a resilient element (3), for example, for an operating current of a switching element which switches an electric or hybrid motor vehicle. In order to be able to produce the switch contact subassembly (1) in a cost-effective and simple manner, there is provision according to the invention for the switch contact subassembly (1) to have a contact bridge retention member (4), the contact bridge retention member (4) having a securing base (14) for securing to an actuation member (15) for the switching element and at least one retention member (17) for positioning the switch contact bridge (2).
