Claims

[Scope of utility model registration request]

An operating shaft equipped with a main gear to which the rotation from the drive motor is transmitted via a reduction gear train, a slip means, etc., and a cam groove for the motor and a time setting cam mounted on this operating shaft on a part of its circumferential surface. a switch operating cam having an annular cam portion with grooves arranged in parallel in the axial direction; and a motor drive cam arranged in parallel in the axial direction of the operating shaft corresponding to the motor cam groove and the time setting cam groove, respectively. The motor drive switch means is provided with a switch means and a time limit setting switch means, and the motor cam groove is provided with a small angle shift in the time setting direction from the time setting cam groove. A contact opening/closing mechanism for a time switch device, characterized in that it operates before the switching means.
