Series Description

The Intermatic Models K and LC Photo Switches are universally employed to control lighting loads in response to available natural light. Each will turn on at dusk and off at dawn, and each may be connected to directly switchloads up to its continuous rating or to switch larger loads through relays or contactors. Stem mount types (see specifications below) are equipped with a 1/2 in MNPT nipple and locknut for mounting to a weatherproof box or conduit body.Stem/swivel mount types attach in the same manner, but include a swivel for directional aiming.
