Abstract: A push button switch is disclosed having a case in which fixed contacts are arranged on an inner bottom surface of the case. A pair of terminals, formed integrally with the fixed contacts, project through the case and into a pair of recesses having vertical walls formed in a lower portion of the case. The terminals projecting into the recesses are both bent at substantially right angles to said fixed contacts so as to be arranged along the vertical walls of the recesses. The pair of terminals are thus formed to be in a same plane and enable the push button switch to be installed in a printed circuit board by an automatic inserter for radial lead type electronic parts.
