Claims

[Scope of utility model registration request]

a dial gear which is engaged with a pinion connected to a drive device and is rotatably supported; a dial which is fitted to the dial gear and is coupled via a clutch spring and has a fixing means around the periphery that corresponds to a time scale; , an open setter and a close setter that are detachable from any position on the fixing means and each have a drive protrusion, and are engageable with the respective drive protrusions of the open setter and the close setter. an opening/closing shaft in which an opening cam and a closing cam are fixed at one end at intervals and rotatably supported; and a contact cam which is fixed to the other end of the opening/closing shaft and engages with a contact device to connect and separate it. In a time switch equipped with
The dial gear and the dial are provided so as to be slidable in the axial direction via a return spring, and the dial gear and pinion are normally in mesh with each other, and by pressing the dial and sliding it, the opening setter and the closing setting are set. A time switch characterized in that the drive protrusions of each setter are engaged with an opening/closing cam, and the dial gear is disengaged from engagement with the pinion.
