Our popular HSC110SS sunset switch is designed to automate outdoor lighting, improving the energy efficiency of homes and businesses by ensuring that lights are only on when they are needed. With four operating modes to choose from, the HSC110SS gives electricians the flexibility to create a custom outdoor lighting program that suits the specific needs of the client or setting. Possible applications for sunset switches include walkways, verandas, courtyards and car parks. Our sunset switch provides ON/OFF control using a photo-electric sensor that detects the ambient light level and switches the relay accordingly. Unlike many sunset switches that need to be calibrated on-site, the HSC110SS comes auto-calibrated from the factory. This feature, along with a warm up time of only 30-seconds, allows for quick and easy installation. The unit has a form factor that can be retrofitted directly onto HPM bases. This makes it easy to replace existing units with our model for upgrades or repairs. Our weatherproof sunset switch is supported by rugged construction and an IP66 ingress protection rating, providing peace of mind for outdoor installations. Refer to the product manual for helpful information on how to protect and maintain this IP rating.
