ABSTRACT:
A programmable timer power switch unit for use with a battery includes a power switch receives power from the battery and switches the power to equipment. The unit also has a charge-discharge detector connected to the battery to detect a potential charge of the battery and a vibration-pressure detector which detects any movement of or sounds from the motor. There is a timer-control logic which is connected to the components and disables the power switch when any problems are detected. The unit further includes a programmable delay switch. The purpose of this switch is to allow the equipment to run during a pre-selected item. Also, there is a manual override switch for overriding the timer-control logic when necessary.
