Abstract
There is provided a plunger switch capable of achieving a self-adjusting mechanism in a simple structure without loss of reliability by mounting a self-adjusting mechanism using a ratchet outside a housing space for movable and fixed contacts. The plunger switch has a switch body divided into blocks, and an attachment member which has a wire spring to be engaged with a ratchet formed on an outer wall of the switch body in order to pierce a plunger therethrough. The switch body is mounted in a predetermined mount position through the attachment member.
