Abstract
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.
