FIELD: chemistry.
SUBSTANCE: invention relates to the safety microswitch (1) for use in vehicle electronics. The switch contains a housing base (3) from which a motionless contact bus (5) moves out and a contact bus (6) with a mobile contact (9) and bimetallic switching disk (7), attached to it. PTC-resistor (29) is made to contact directly with bimetallic switching disk (7) by means of a spring of compression (28) and is electrically connected in such a way that due to heat generated by the PTC resistor the bimetallic switching disk (7) in case of actuation remains in the open position.
EFFECT: creation of manufacturable microswitch with high functional reliability due to prevention of undesirable switching back of a bimetallic disk.
