Claims

[Claims for Utility Model Registration] A rotating shaft rotationally driven by a drive source, a timer cam that rotates with the rotation of the rotating shaft, and a timer cam that is provided between a power source and a controlled device and that is provided as the timer cam rotates. A time switch that shuts off the power when the set time has elapsed; A control switch that is installed between the power supply and the controlled device to turn on/off the power to the controlled device; and a control switch that turns off the power to the controlled device during the set time. energization state selection means for selecting and setting the energization state of the energization state from among a plurality of different energization states; A time switch having a control switch operation mechanism that acts on the control switch in a preselected and set energized state, and angular position detection that detects when the rotation of the rotating shaft or time cam reaches a certain angular position. a mechanism; and the above-mentioned device so that, upon detection of the constant angular position of the angular position detection mechanism, a predetermined energization state among the plurality of energization states is achieved regardless of the energization state selected in advance by the energization state selection means. A time switch comprising an energization state conversion mechanism that operates a control switch operation mechanism.
