ABSTRACT:
A push button switch has a stem having a thin flange without requiring fabrication of synthetic material, thereby realizing a push button switch having good productivity and high reliability. To this end, a push button switch has a housing (10) having an opening, a fixed contact (17) exposed on the inner bottom surface, a movable contact (13) disposed to face said fixed contact (17), a stem (15) having a flange portion around its main body and being mounted on the housing (10) movably in an up-and-down direction, the movable contact (13) being contacted with the fixed contact (17) when said stem (15) is lowered, and the stem (15) being formed by a first metallic material (21) and a second metallic material (22), the first metallic material (21) having a through hole (21a) surrounded by a tapered surface (21b) and chiefly constituting the flange portion of the second metallic material (22) being press-fitted into the through hole (21a) on the first metallic material (21) so as to be press-fixed on the tapered surface (21b) of the first metallic material (21) through press processing.
