12V photoswitch

This photo-switch (light-sensitive switch) senses the ambient light level and will switch external devices on or off at night and in the morning, depending on which leads are connected to the device.

It is called a 'Twilight Switch" by the manufacturer as its primary use is in switching power on and off at dawn and dusk.

The control circuit must be powered by 11V - 14V, power consumption is only 2mA / 35mA (relay off/on) so it can be powered by a small 12 volt battery.

The maximum power supply that can be controlled by the photo switch is 25 Volts / 3 Amps.

The switching relay has a delay of approximately 3 to 4 seconds after the photocell has registered a change in light level.

Common uses are for garden lighting and security applications. The sensitivity of the photocell (on top of the unit) can be altered by partially covering it. Instructions are included.
