Pulse-Width-Modulator allows variable heat output to grips. CANNOT be used for heated clothing which usually draw too much current and would cause the built-in circuit breaker to trip. Has a click-detent off position, a feature absent from our previous aluminum bodied controller. Panel mount only, just the knob will show above the panel mount location you choose. NOT intended for handlebar mounting. Easy two wire installation, red wire is for power source, black is output to the grips.

Eliminates the toggle switch and resistor for any heated grip installation. Counter-clockwise is no heat, clockwise is increasing the heat output to the grips. Heat changes from a lowest setting of 25% voltage "on" time and gradually intensifies to 99% voltage "on" time. Built-in automatic circuitry has a 4 amp circuit-breaker which prevents use for heated clothing, CANNOT be used for heated clothing. Dimensions: Maximum housing is 2-1/8"" diameter. Maximum housing depth is 1". Black control knob is approximately 13/16" diameter. Lead wires are 9" long fine-stranded 20 AWG irradiated PVC insulated tinned copper. Housing back side is silicone sealant potted for weatherproofing. No LED indicator light supplied but you can fit any 12v LED in "parallel" to black wire if you desire.

Red wire is the "power-in source" and the black wire is fed out to the heated grips. 

This will NOT fit in our handlebar mount switch housing which is intended only for our stock toggle switch.
