A switch comprises a switch housing including a cover, a terminal block welded to the cover and a fixed contact point therein, a moving block provided with a boss for fitting a manual shaft of an automatic transmission and a movable contact point corresponding to the fixed contact point and movable to the switch housing and elastic seal rings interposed between inner and outer peripheral surfaces of each of the terminal block and the cover, and the operation portion. One of the cover or the terminal block is formed of a colored, laser transmissive material and the other is formed of a laser non-transmissive material. The terminal block and the cover are automatically aligned with the moving block by an elastic force of the seal ring and a thermal welding part is circularly formed by means of a laser beam on the side of the outer periphery in each of the terminal block and the cover to be aligned for coupling the terminal block with the cover to fix the alignment.

Switch and welding method of same

A switch comprises a switch housing including a cover and a terminal block coupled with the cover. The cover is formed of a colored, laser transmissive material and the terminal block is formed of a laser non-transmissive material. A thin part is circularly formed in the cover formed of the colored laser transmissive material on the periphery side of the switch housing and is thinner than another part of the cover and a thermal welding part is circularly formed along the thin part by means of a laser beam for coupling the terminal block with the cover.
