ET1700 Series


The ET1700 Series 7-Day Electronic Time Switches feature independent 7-day programming to provide flexibility for applications where load switching differs each day of the week. These time switches provide dependable and uncomplicated performance, plus to-the-minute programming for accurate load control and reduced energy costs. Up to 28 setpoints or events can be present to automatically repeat. The program can be disabled at any time by placing the time switch in the Manual operating mode. Control buttons provide manual control of each circuit independently regardless of the operating mode. All models contain industrial-grade AAA alkaline batteries to provide time keeping and automatic carryover for a minimum of three years. The batteries are easy to replace and do not require removing the time switch mechanism or field wiring. Each time switch is housed in a lockable enclosure to protect against vandalism and unauthorized tampering.

New Product Highlights


The Intermatic® line of occupancy sensors are engineered and tested for long-lasting performance. In-Wall and Ceiling Mount sensors in both PIR (infrared) and dual (PIR/ultrasonic) technologies can monitor virtually any area within a building, providing solutions for any retrofit or new construction project. They utilize zero-crossing technology to suppress inrush current impact, supplying reliable ON/OFF sensing no matter the lighting technology.


The Intermatic® ICUBE™ Adaptive Defrost Module cuts defrost cycles--and utility bills--for the food service industry. Designed by Grässlin by Intermatic for commercial walk-in coolers and freezers, the smart-sensing technology behind the ICUBE™ continuously monitors evaporator coil temperatures and only allows defrosting when necessary at the next programmed timer interval.

Surge Protective Device Group Shot

The Intermatic® Surge Protective Device with Consumable Modules covers 100% of a home’s big investment equipment, from appliances and computers, to HVAC equipment and TVs. The Surge Protective Device uses replaceable Consumable Modules that allows homeowners to easily and safely replace a module when the built-in LED light indicates it has been compromised.
