Abstract
A subminiature switch structure particularly adapted for cooperation with integrated circuits as may, for example, be employed in an electronic watch including a restrained spring wire manually movable by resilient bending from normal spring loaded engagement with a first terminal into wiping engagement with a second terminal.
Claims8
An electronic switch comprising:
- a first terminal post,
- second and third terminal posts spaced from said first post and closely separated from each other,
- a spring wire extending between said second and third terminal posts and wrapped partially about said first terminal post,
- means disposed on the opposite side of said second and third terminal posts from said first terminal post engaging said wire and limiting lateral movement of said wire thereat,
- said wire being adapted for deflection to normally resiliently hold same against said second terminal post and further deflection by the application of an operating force between said first terminal post and said second and third terminal posts to deflect the wire out of contact with the second terminal post and into contact with the third terminal post.

An improved miniature switch comprising:
- an insulating base plate,
- a first terminal post mounted on top of said base at a first end thereof and having a groove thereabout,
- a captive post having a groove thereabout mounted on top of said base at a second end thereof,
- a second terminal post mounted on top of said base between said first terminal post and said captive post adjacent the latter and forwardly of the base from a line between said first terminal post and captive post,
- a preformed spring wire curved about said first terminal post and resiliently compressed between said second terminal post and an upright on said base toward the rear thereof with a wire end extending into the groove in said captive post, and
- a third terminal post mounted on top of said base slightly rearwardly of said base from said second terminal post on the opposite side of the wire from said second terminal post whereby application of a force to the wire rearwardly of the base between said first and second terminal posts actuates the switch to resiliently deflect the wire into engagement with the third terminal post and out of engagement with the second terminal post.
