Abstract

PURPOSE: To control a pump by directly triggering a solenoid contactor on an output of an electronic timer on the basis of detected live pressure switch, thereby providing a quick response and small size in comparison with a relay circuit.
CONSTITUTION: When a tank is vacant, a pressure switch 5 is closed. In the above condition, turning a power source on, a high frequency oscillator circuit which feeds a high frequency pulsated gate current to the primary thyristor 13 via a pulse transformer 23 is operated. Consequently the primary thyristor 13 is kept on to excite a coil 2b of a solenoid contactor, thereby closing its contact point 2a to serve pumping. Presently boosted water pressure opens the pressure switch 5, which on the contrary to the above mentioned effect, turns the primary thyristor 13 off to stop a motor 1. A quick response can be expected by using an electronic circuit.
