PUSH BUTTON SWITCH FOR ELECTRONIC WATCH |
摘要 |
<p>A push button switch for setting the time display of electronic timepieces utilizes a conductive elastomeric material such as silver filled silicone rubber as a conductive spring in its moving contact. The elastomer biased contact may be seated in a port in the watch frame and bonded thereto to make the frame waterproof. Momentary electrical contact is secured by pressing the moving contact against a metal contact portion of the printed circuit time keeping substrate within the watch frame. The watch frame is electrically connected to ground in the electronic watch circuit.</p> |
