12V 10A Dark Activated Switch by LM324

The circuit is a combination manual switch and automatic dark-activated switch. It is designed to control up to 10 amps of 12V lights. A pair of high-intensity white LEDs are included in the circuit for built-in lighting. The circuit includes a low voltage disconnect circuit that prevents excessive battery discharge on battery operated systems. The DAS1 is ideal for solar powered lighting systems, it can also be used for line powered and automotive/marine applications. External 12V lights consisting of white LEDs, incandescent lamps and/or fluorescent lamps can be driven by this circuit.
