    Illuminated Switches

    This Flex-a-lite illuminated 3-way switch gives you the option to override the fan controller and adapt to the demands of your ride. One illuminated switch provides cockpit control for turning the fans on at 100-percent for tow mode, turning the fans off for water crossings, or allowing the controller to do its job.

    Flex-a-lite part number 31143 provides three functions in one switch:
  • When switched to Tow Mode the illumination is blue. The fans are activated at 100-percent power, regardless of coolant temperature. This can help better regulate temperatures when towing heavy-loads and extra cooling for steep hill climbs is desired.
  • In the neutral position there is no illumination and the fan controller will determine when the electric fans are needed. Fans will come on at the coolant temperature you determined or when the air conditioning is on.
  • In Water Crossing Mode the illumination is red. Fans are turned off, allowing you to cross deep water without damaging the fan blades or sucking up water. Water Crossing Mode can be used for any situations where you want the fans to remain off regardless of coolant temperature

  • Specifications:

    Rated 5 out of 5 by from Good product This switch was surprisingly well made. Thick wires, switch worked well, instructions are clear. I used this to power the fan on while I was breaking in my big block chevy camaro. I can see this being useful to run the fans when needed instead of letting the controller run them.

    Is this switch a SPDT or DPDT?

    Asked by: JeepNC
    This is not a true DPDT switch as it shares the main power terminal.
