Abstract
A time switch that provides a convenient time setting method through a sub-dial that can be rotated clockwise or counter-clockwise. A ratchet device is constructed of multiple ratchet teeth formed at specific intervals on the rear surface of a drive gear, and pawls that extend from a pinion gear, the tip portions of the pawls engaging the multiple ratchet teeth. The ratchet device does not slip when the torque applied by the motor is sufficient to rotatably drive the dial, but slips when the torque applied to the ratchet device from the dial is greater than that applied by the motor. A control knob, which is attached to the tip of the cam shaft, may be turned to control the rotation of a switching cam which sets contact points to on or off positions.
