Claims

[Scope of Claim for Utility Model Registration] (1) An electrode substrate is fixedly installed, is positioned opposite to the electrode substrate, and rotates in conjunction with manual rotation of a set dial to change the relative positional relationship with the electrode substrate. a control switch plate that can be operated and driven in conjunction with the motor, a control circuit that generates a drive signal for the motor, and a first, second, and third control contact that is connected to the control switch, respectively; first, second, and third electrodes integrally formed at different radial positions on the plate and sliding toward and away from the first, second, and third control contact pieces, respectively, on the electrode substrate; a first circuit that forms a pattern, is switched when the set dial is set and reset, and controls supply and stop of a drive signal to the motor of the control circuit;
The control switch is composed of the first and second control contacts and the first and second electrode patterns, and is switched when the set dial indicates a certain remaining time, and is activated to control the motor of the control circuit. A second control switch that switches the drive signal to a high frequency to rotate the motor at high speed is comprised of the first and third control contacts and the first and third electrode patterns. Crystal timer. (2) In paragraph 1 of the claims for utility model registration,
A crystal timer characterized in that a sounding device generates a notification sound when the set dial times out.
