Abstract
Disclosed is an apparatus for controlling a solenoid switch connecting a power supply to a load. The apparatus constantly monitors the level of output voltage of the power supply, and accordingly controls the engagement or disengagement of the solenoid switch. Initially at the time the power switch is just turned on, the solenoid switch would not be engaged until the voltage has reached a predetermined level. After the solenoid switch is engaged and power is delivered to the load, the apparatus would disengage the solenoid switch when the voltage level of the power supply goes beyond an upper limit or below a bottom limit. Utilizing the apparatus, the power input to the load can be kept in a desired range.
