Photocell (Dusk-to-Dawn) Switches
Cord-mounted light-level switches with an inline plug and socket: the lamp turns on at dusk and off at dawn with no wiring work. Built for sign and billboard installers, street and garden lighting contractors, and insect-killer distributors who need automatic operation on existing plug-in fixtures.
GK-AC-220V Dusk-to-Dawn Switch, 600 W
For street lights, courtyard lights and insect killers, the applications the factory lists. It is described with high sensitivity, strong anti-interference, and delayed light-sensing to ride through brief light changes.
| Operating voltage | 85–277 V AC |
|---|---|
| Load | 600 W |
| Switching thresholds | ON below 5 lux · OFF above 15 lux |
| Standby draw | < 0.2 W |
| Ingress marking | IP66, the factory's own marking, not third-party tested |
| Working temperature | −10 °C to +35 °C |
| Size | 83 × 54 × 28 mm |
Do not rely on the IP66 marking where water could reach a live fitting; tell us whether the switch sits under an eave, inside a sign box or fitting, or fully weather-exposed, and we can quote independent testing of this model.

Notes
GK-AC-220V: for a 600 W load, check the switch against your installation conditions. The IP66 marking is declared by the factory, and no independent ingress test exists for this model. The sealed housing is designed for street and courtyard lighting, but the marking does not establish tested IP66 performance. Confirm protection for the actual exposure, or specify a housing with a test report behind it.
Read every IP number on this site the same way: without a named test report beside it, it is a manufacturer's marking, not a tested rating.
