A programmable timer power switch unit with emergency override reset for use with a battery includes a power switch which receives power from the battery and switches the power to equipment. The unit also has a plurality of voltage detectors connected to the battery to detect a plurality of voltages and a vibration-pressure detector which detects any movement of the motor. There is a timer-control logic which is connected to the components and disables the power switch when voltage 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 time. Also, there is an auto/manual override switch for overriding the timer-control logic and providing a short delay time prior to disconnecting the unit in order to protect any memory intensive electronic equipment from intermittent drop-outs such as when the engine is started.
