Wide Open Throttle Switch

Part Number 600-2

This product is designed for use with QFT’s Professional Series and Holley Dominator® (model 4500) carburetors. On the back side of the micro switch is a wiring schematic indicating proper terminal use for normally open so the switch will complete the electrical circuit once the switch is closed.

Installation is straight forward, remove the hold down nut on either corner opposite the throttle shaft (either primary or secondary). Install as shown below, tighten hold down nut.

Check the switch for engagement at wide open. There should be an audible click or use a volt/ohm meter to confirm activation. If the switch doesn’t activate, the left hole of the micro switch is slotted to realign if necessary.
