Abstract
A dual in-line package miniature electrical switch module has its active members, the contact members and sliding actuators, mounted on a unitary frame member to minimize misalignment problems. The cover serves primarily a protective function. The contacts have integral terminal pins and clamp to an edge of the frame to simplify assembly. A substrate having an electrical circuit pattern applied on one or both major surfaces can be contacted and clamped by the contact members against the bottom of the frame to form an integral switch and circuit module, such as an attenuator switch. Two or more sliding actuators may be rigidly interconnected to form a gang unit.
Claims7
An electrical slide switch of the type having a cover which leaves exposed one or more sliders for actuating make-or-break contact members inside the switch, CHARACTERIZED IN THAT
- said switch comprises under said cover a unitary frame member having a base which forms a floor and having at least two partitions extending from said base to form between them at least one chamber for receiving said contact members, said partitions being adapted at their free edges remote from said floor to form a slot for holding and guiding said sliders, said contact members comprising a spring member which is pressed against an anvil member by action of a cam surface on said slider engaging a cam-follower surface of said spring member, and said contact members each including a clip portion by which they are resiliently held to the edge of said base.
