Explosion-proof switch and explosion-proof electrical device

Abstract

The invention provides an explosion-proof switch and an explosion-proof electrical device. A first sealing element is in seal contact with a switch element and an inner wall of a first receiving cavity, a lead cable has an end connected to the switch element and an end penetrating through a cable hole and stretching out of a first protective shell, and a second sealing element is arranged in the cable hole and in seal contact with an inner wall of the cable hole and the lead cable. An assembly clearance between the switch element and the first protective shell and an assembly clearance between the lead cable and the first protective shell are sealed to improve the sealing performance of the explosion-proof switch, thus avoiding a short circuit or an explosion.
