Miniature dual in-line package electrical switch
First Claim
1. An electrical switch comprising:
- A. insulating base unit means including first and second conductive terminal means and insulating wall means defining a cavity therein about said terminal means, each said first and second conductive terminal means comprising an external terminal section and an internal stationary contact section, said first and second conductive terminal means lying in a pole plane with said contact sections being spaced from each other,B. movable contact means disposed in said cavity and in said pole plane, said movable contact means having a first end portion, a first intermediate portion for engaging said first stationary contact section, a second intermediate portion adjacent said first intermediate portion for forming a cam follower and a second end portion, andC. cover means for closing said base unit means and including support means with capture means for engaging said first end portion of said movable contact means thereby to maintain the said first intermediate portion in engagement with said first stationary contact section, said cover means additionally including actuator means capatured by said support means and rotatable therein between first and second positions, said actuator means including a depending cam means for engaging said cam follower whereby said second end portion of said movable contact is, respectively, spaced from said second contact portion in a first position of said actuator means and forced into contact with said second contact portion in a second position of said actuator means.

Abstract
An electrical switching device of the dual in-line package type. A multiple-pole switching device contains a plurality of independent switching elements aligned on individual pole planes. Each switching element includes first and second terminals and stationary contacts centered on the pole plane. A movable contact engages a first stationary contact and is held in position by a boss on a cover actuator. An actuator, captured in the cover-actuator, includes a cam that engages an intermediate portion of the movable contact to move the second end of the movable contact into engagement with the second stationary contact to complete an electrical circuit. The cam and movable contact are configured to produce a detent action as the actuator moves between open and closed positions.
