Push-button switch with bridge section integrally connecting movable contact and fixed contact

Abstract

A push-button switch including a housing which is integrally molded with a first metal plate and a second metal plate. The first metal plate includes a fixed contact, and the second metal plate includes a main portion, a bridge section extending from the main portion, and a bowl-shaped movable contact on a forward end of the bridge section. The housing is provided with a recess for exposing the fixed contact on the inner bottom face thereof, a plurality of caulking walls formed in an annular form around the recess, and gaps for relieving nonuniform thickening of the caulking walls which occurs at the time of caulking. The bridge section is folded such that the bowl-shaped movable contact covers the recess, and a peripheral edge portion of the movable contact is then fixedly caulked with the caulking walls.
