ABSTRACT:
Electronic watch is constructed with a ceramic substrate as the principal support of the time computer and memory. The substrate may also carry other devices such as printed circuitry, oscillator and the optical display. Battery connection contacts are positioned on one side of the substrate. A resilient electrically conductive pad is positioned against the contact, and the battery rests against the pad to provide electrical conduction over a large area and to spread shock loads from the battery across a large area of the substrate to both maintain electric contact and minimize mechanical shock.
