Abstract

PURPOSE:To reduce the space of fitting by installing two timer circuits, which turn on and off repeatedly at optional intervals of time, in one housing. CONSTITUTION:Oscillating circuit 20a oscillates at a frequency based upon a time constant set by time constant circuit 27a, frequency dividing circuit 21a divides the frequency at a frequency division ratio set with frequency-division ratio change- over switch 29a, and counting circuit 22a counts its output pulses. Then, when the counte value reaches a set value, the output of output terminal 30a is inverted to level L and while the excitation of relay 37 is released, the output of output termina 31a is inverted to level H, so that while the 1st timer circuit 18 is reset, the counting operation of the 2nd timer circuit 19 will be started. Then, when the count value of counting circuit 22b reaches a set value, the 1st timer circuit 18 is allowed to count up and relay 37 is excited.
