Abstract (en)
To achieve an energy effective switching between different loads at low cost there is provided a tristable relay using a core element (10) having a coil (12) for magnitisation of the core element (10). Further, a member (14) having at least one permanent magnet (16) defining a first and second magnetic pole region is arranged with respect to the core element (10) such that a relative movement between the member (14) and the core element (10) is possible. The relative movement is used to achieve switching in a tristable relay, e.g., for application within a no-frost refrigerator/freezer. <IMAGE>
