NSi has been an industry leader in electrical connectors, wire management products and related electrical components since the mid 80’s, introducing many new and innovative products and installation practices to the industry. Many of our products (such as Polaris brand insulated connectors) are now accepted as the industry standard and used by electricians everywhere on a daily basis. We are exceptionally proud of our reputation for quality and the contribution that we have been able to make to ensure that the jobsite is safer and the finished installation more professional.

TORK ® brand products, manufactured in the company's Mount Vernon facility, is NSi Industries' largest brand, covering the categories of Electromechanical and Digital Time Switches, Signaling and Alert Devices, Pool and Spa Controls, Residential Timers, Photocontrols and Occupancy Sensors. For over 85 years, TORK brand recognition and reputation for quality and design make it the most specified brand in the industry. The TORK brand has a rich history beginning in the 1920s when the company introduced the first electromechanical time switch to the marketplace. Currently, TORK's time switches maintain energy efficiency through lighting control in such high profile places as the Empire State Building, Washington DC Parks and Recreation, The Triborough Bridge, The Met Life Building and many more institutions across the country. As the most specified brand of time switches in the industry, TORK enjoys the hearty respect of engineers and project planners across all channels of distribution.

In the past several years, NSi has introduced a number of TORK time switches, in-wall and plug-in timers to meet increasingly specific needs in the marketplace. We've also added a line of installer-friendly pool and spa panels and time switches, and are proud to offer essential pool safety products that meet and exceed federal requirements for safe pools. We look forward to designing and engineering more of our Responsible Energy products, helping save money and the environment through responsible and minimal use of energy.
