Abstract
A time switch that provides a convenient time setting method through a sub-dial that can be rotated clockwise or counter-clockwise. A gearwheel set, through which motor torque is conveyed to a dial, includes a ninth drive gear and a ninth shank gear which is joined to a step shaft on which the ninth drive gear rotates. A circular depression is formed within the rear side of the ninth drive gear, the inner perimeter on which are formed multiple ratchet teeth at uniform intervals. Ratchet pawls, which extend from the shank portion of the ninth shank gear, engage the ratchet teeth to form a ratchet mechanism that does not slip when the torque applied by the motor is sufficient to rotatably drive the dial, but that slips when the torque applied to the ratchet mechanism from the dial is greater than that applied by the motor.
