FIELD: electricity.
SUBSTANCE: magnets have the same polarity at edges faced to each other; ferromagnetic separating plate is located between magnets, its size is less than surface of magnet edges faced to each other. At that actuator can impact on switch with movement gap.
EFFECT: reliable process of switching from certain switching state with saving in case of occurrence of vibrations or relative movements between separate elements of desired switching state.
