In the IC card connector of the present invention, a single supporting projection is provided on a bottom wall of a housing, so when the housing is put on a circuit board, it can be supported at three points: one point of the supporting projection and two points of terminal portions of pin terminals. Therefore, even in the event of a difference in height of the supporting projection, there is no fear of the terminal portions being lifted and it is possible to keep the terminal portions close to a conductive pattern, whereby the terminal portions can be soldered to the conductive pattern in a reliable manner.

IC card connector and IC card connector mounting structure

The present invention relates to a push button switch which is capable of preventing deformation of a belt-like metallic plate serving as a terminal of the push button switch during its insertion molding process into the housing of the push button switch. To this end, a push button switch comprises a square housing, a belt-like metallic plate inserted in the housing so as to penetrate the housing, the housing having an outer wall from which the belt-like metallic plate protrudes outward, the belt-like metallic plate having an inner portion exposing from a bottom surface of the housing and an outer portion extending outward from the outer wall of the housing, and the outer wall being planed-off obliquely at a portion where the belt-like metallic plate protrudes. Therefore, the span of the belt-like metallic plate becomes short. Thus, the push button switch can be made compact in size.

Push button switch

A method of molding a case for use in a push-button switch as employed on a television receiver, video tape recorder, or the like. A contact plate having a central fixed contact and two opposite fixed contacts is mounted between an upper die and a lower die. One of the dies has a central support portion and two opposite support portions. In one embodiment, the central fixed contact and the opposite firxed contacts are pressed against the central support portion and the opposite support portions, respectively. A locating pin that tapers off is pressed against the central fixed contact. Two other locating pins are pushed to the vicinities of the opposite fixed contacts.
