According to the invention, secure control of electrical actuators and/or sensors and/or users (V1, V2, V3) in an electrical appliance can be achieved, wherein at least two switch bodies (SW1, SW2) operated corresponding to an AND link are controlled for effective switching of said actuators and/or sensors and/or users (V1, V2, V3) by means of bistable control bodies (SG1, SG2), which are in an activated state (set status) in which the switch bodies (SW1, SW2) are effectively switched by supplying with a continuous signal (DS) and a pulse signal (IS) supplied during the duration thereof and can only be put in the switched off state (reset state) by switching off said continuous signal (DS) in which the switch bodies (SW1, SW2) are switched off and which can not be returned to the activated state (set state) just by once again supplying the continuous signal (DS). |
