Overview

The NSi Industries Button Flush Mount (SKU 3002) is a precision-engineered photocontrol designed for commercial and industrial lighting applications, including state/county DOT roadway and bridge lighting, warehouses, and general commercial facilities. This flush mount switch operates within a 208-277V AC range (50/60Hz) and supports tungsten (3470-4620W), ballast (2080-2770VA), and LED (1040-1385VA) loads, making it compatible with a wide range of lighting systems. Its conformal-coated cadmium sulphide (CdS) photocell resists moisture and airborne contaminants while responding to light spectra similar to the human eye, ensuring accurate operation even in harsh environments. The unit features a delayed OFF response (3-5 seconds) to prevent false switching from transient light sources like passing vehicles or lightning, and an ON/OFF threshold of 1-5 foot-candles (turn-ON) and 3-15 foot-candles (turn-OFF), adjustable via a slide cover without tools. Constructed from UV-stabilized polypropylene with a permanent color and clear acrylic window, the housing provides high-impact resistance, flammability safety, and electrical integrity. The DC relay offers positive snap-action switching, reducing contact bounce and extending operational life to 6,000 cycles. Additional features include 360-joule MOV surge protection exceeding NEMA/ANSI requirements, solid brass locking prongs for corrosion resistance, and a temperature range of -40°F to +140°F (-40°C to +60°C). The switch fails in the ON position for safety and carries a 3-year warranty. Ideal for municipalities, commercial buildings, and industrial sites, the Button Flush Mount integrates seamlessly into existing electrical systems with 9" leads (#16AWG, 105°C rated) and meets UL773, ANSI C136.10, and EEI NEMA standards. Its durable design and precise light-sensing technology deliver reliable, energy-efficient operation for outdoor and indoor lighting control.
