Abstract
A single in-line package switch for individually switching a number of terminals to establish separate conductive paths with a common terminal. The switch comprises an insulating housing with a number of terminal pins exceeding the number of switching poles by one. The insulating housing has an internal cavity corresponding to each terminal switch and recesses in certain of the cavities for receiving rotary actuators. A cover and base clamp a common strip portion of a contact finger structure and bias cantilevered contact fingers into engagement with internal contact end sections of the terminals. One of the contact fingers permanently contacts one terminal connected to a reference potential, thereby establishing a fixed electrical path between the common strip portion and the reference potential. Each actuator includes a planar portion for engaging a free end section of the contact fingers for producing the switching action. The actuators and insulating base have coacting means that provide detent and snap action.
