Displacement detecting switch device

摘要

A displacement detecting switch device is assembled with ultrasonic welding techniques, so that easiness of assembling work for it is further increased. The device comprises a switch body including a cover body and a base plate; an operation lever disposed pivotably outside of the switching body; and a movable plate disposed inside of the switch body and linked with the operation lever. There are disposed a first joint portion and a second joint portion formed by ultrasonic welding between the cover body and the base plate and between the operation lever and the movable plate, respectively.
