Intermatic 1000-Watt Button Thermal Photocontrol, Gray

The K4000 Series Fixed Position Mounting Photo Controls are thermal-type photo controls that fit into a standard outlet box, post lamp or wall pack. The photo controls provide dusk-to-dawn lighting control, along with a delay action, which eliminates loads switching OFF due to car headlights and lightning. The thermal-type controls feature a cadmium sulfide photocell and a sonic-welded polycarbonate case and lens to seal out moisture. The design utilizes a dual temperature compensating bi-metal and composite resistor for reliable long-life operation over ambient temperature extremes.
