ABSTRACT:
A recessed push button in the back of an electronic watch is sealed and returned to its normal position by a resilient O-ring gasket, and retained in a recessed opening in the watch case by a spring retaining clip. The clip has a keyhole slot transversely slidable around a groove in the push button stem, with a retaining tab locking the clip in position. A first conductive member maintains contact with the clip, holding it in position, and a second conductive member is spaced from and contacted by the clip when the push button is depressed.
