Abstract
The pusher and switch device is employed in electronic watches for actuating, for example, a display light. The pusher includes a crown portion, a stem portion extending through the wall of the case and having an intermediate section on the inside of the case which cooperates with a single stamped spring to provide axial movement of the stem. In addition to permitting axial movement of the stem, the spring arrangement also provides electrical contact to ground the stem to the case. A sealing element or gasket is held in an annular groove formed in the stem which contacts the internal surface of the case to provide for water resistant construction.
