Toggling Relays - Convert Momenrary Switch to Latching

The FOG-901 and FOG-901NP are advanced relays designed to allow a momentary switch to act as a latching switch. 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.

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. (Inductive loads should be suitably de-rated and fitted with a back-emf diode before connection to the FOG-901 or FOG-901NP).

• One single wire to the switch (other side of switch is earthed locally)
• Switch lights up dimly when output is off – easy to spot it in the dark (LED in switch required)
• Switch lights up brightly when output is on
• Uses ANY momentary switch (illuminated or otherwise)
• Output up to 5A for the FOG-901 or 15A for the FOG-901NP
• Self-cancelling
• Hermetically sealed in epoxy resin – IP68 rated (FOG-901)
• Economical bare-board version available (FOG-901NP
• Small size enclosure for FOG-901 (40 x 40 x 20mm)
• Small size PCB for FOG-901NP (35 x 28 x 15mm)
• Extremely reliable
• 12V supply

Applications include:

• Self-cancelling fog-light control
• Demister control
• Overdrive solenoid control
• Automotive/Marine lighting
