FIELD: electrical switching devices.
SUBSTANCE: device comprises base (B) and key (T), pivotally connected on two ends relative to base (B), so that key (T) can be in idle position, rotate around first axis (G1) or around second axis (G2) or move in direction z (Z), and comprises first limit microswitch (MS1) and central microswitch (MSC), wherein the activation angle of the first limit microswitch is greater than the first activation angle of the central microswitch, and thus determining at least three intervals depending on the angle of rotation of the key around the first axis: an interval in which none of the first limit and central microswitches is activated; interval in which only the central microswitch is activated; and an interval in which both of the first limit and central microswitches are activated.
EFFECT: elimination of ambiguity of function when switching device is pressed.
