Abstract
A multifunction analog electronic watch includes a battery, a circuitry block and a base plate made from a polymeric other electrically non-conductive material. A switching device for controlling application of the voltage from the power source to the circuitry block includes a switching member and two electrode patterns. The first electrode pattern is electrically coupled to the power source and the second electrode pattern is electrically coupled to the circuitry block. The switching member, which is normally biased away from the first electrode pattern and second electrode pattern is operable in response to external pressure for contacting the first electrode pattern and the second electrode pattern so as to provide an electrical path between the first electrode pattern and the second electrode pattern.
