<p>W-113 MANUALLY-ACTUATED CONTACT SWITCH ARRANGEMENT FOR ELECTRONIC WATCH Inventor: Werner Richard Baumgartner, a citizen of Switzerland and resident of Orpund, Switzerland A manually-actuated contact switch arrangement for an electronic watch in which an electronic circuit board is mounted on a base plate fitted within a case, the board having a contact extending therefrom which when electrically connected to the case completes a circuit effecting a command or setting function. The arrangement includes a return spring anchored on the base plate. A section of the free end portion of this spring is received in a transverse groove in a push member displaceably seated within a bore in the ease whereby the spring imposes an initial tension on the member to maintain it at a predetermined rest position. By depressing the spring-biased push member, the free end of the spring is caused to engage the contact to close the circuit.</p> |
