PURPOSE:To facilitate operation by coding the signal of a timer time setting switch and the signal of a timer on/off switch to incorporate into one code switch. CONSTITUTION:The timer time setting switch SW4 is formed of a code SW section 4a that selects the on/off of a timer and a timer time setting SW section 4b to set by the operation of a knob 4c. For instance, when the switch SW4 is set to the contact of time t3 of the timer side, binary code data corresponding to the time t3 are inputted to the input ports 1, 2 of an LSI1, and an input signal H is inputted to a port 5. When a timer reset SW2 is turned on once under this condition, the LSI1 outputs after a set time t3, a relay contact 5 is closed to make the load on. In the case of timer off, similar operation can be made by making time setting by the knob 4c at an off side. |
