The FOG-901 and FOG-901NP are advanced relays designed to allow a momentary switch to act as a latching switch. Rated at 12V DC, the FOG-901 is hermetically sealed and watertight and is rated at 5A load, while the FOG-901NP is a bare-board unprotected unit rated at 15A. Otherwise the units are functionally identical. The units were originally designed for use with import vehicles to control the rear fog light from a momentary switch in the dashboard, but they are suitable for controlling any load within the rating. (Inductive loads should be suitably de-rated and fitted with a back-emf diode before connection to the FOG-901 or FOG-901NP).
