Abstract
An electronic timepiece includes a first switch connected to a signal line, a second switch, and a one-shot pulse signal generation circuit. The first switch is inserted into the signal line. One end of the second switch is connected to the signal line at a rear stage of the first switch, and the other end of the second switch is connected to a power source. The one-shot pulse signal generation circuit generates a one-shot pulse signal by using a reference clock signal, and the second switch is controlled by the one-shot pulse signal. The timepiece device can reduce currents flowing in a pull-down resistor or a pull-up resistor when a crown switch is turned on.
