Clutch Starter Safety Switch

A clutch interlock checks clutch-pedal position on an equipped manual transmission. An automatic-transmission start interlock checks the allowed selector position. They serve a similar starting-safety purpose in different systems and are not interchangeable.

The pedal may not reach the switch's required position, or the fault may be in the switch, battery, wiring or another part of the starting circuit. Ford also cautions that a displaced floor mat can interfere with full pedal travel.

The interlock is a safety feature that helps prevent unintended vehicle movement during starting. A faulty circuit should be diagnosed and restored to the vehicle's specified operation rather than bypassed.

Terminal count alone does not establish the mounting, travel or electrical characteristics. Several A-Premium switches have two blade terminals but serve different vehicle applications; choose the one specified for the starting circuit.

The switch must change state at the pedal position required by the starting system. Incorrect mounting or limited pedal travel can prevent the intended signal or allow incorrect operation; use the vehicle's mounting and adjustment procedure.
