Help prevent the engine from cranking unless the clutch pedal is pressed with the Standard Ignition switch NS-127. It is a clutch starter safety switch that is also listed as a cruise control release switch. NS-127 is a direct-fit replacement for many vehicles, among them the 1988-1996 Ford F-150, 1988-1999 Ford F-250 and 1991-1997 Ford Explorer. See the "Vehicles it fits" section for the full list of applications and engine details.
A clutch starter safety switch senses clutch pedal position. It is designed to let the starter circuit close only when the pedal is depressed. As a cruise control release switch, it is intended to signal the cruise system to disengage when the clutch pedal is pressed, on applications equipped with cruise control.
- Copper alloy conductors: provide strong electrical conductivity with low resistive losses.
- 100% tested: every switch is checked to verify both its mechanical and electrical switching performance.
- Controlled manufacturing: experienced professionals build each switch under a full quality-control process, from componentry through the finished product.
- Robust design: high-grade materials are chosen to meet the demanding needs of today's service professional.
Signs this switch may need replacing include an engine that won't crank, or cranks only intermittently, with the clutch pedal fully depressed. Another sign is cruise control that doesn't set or release as expected. These symptoms can have other causes, so diagnose the circuit before replacing the switch.

Frequently Asked Questions
What does a clutch starter safety switch do?
It senses clutch pedal position and is designed to let the starter circuit close only when the clutch pedal is depressed. This helps prevent the engine from starting in gear.
Is NS-127 the right Explorer switch for a 1991-1997 Ford Explorer?
Yes. It is listed for the 1991-1997 Ford Explorer. The "Vehicles it fits" section shows the complete application details for that model and the rest of the list.
Why is it also called a cruise control release switch?
The part is cataloged under both names. On applications with cruise control, the release switch is intended to signal the cruise system to disengage when the clutch pedal is pressed.
How is the switch tested?
Standard Ignition states that its switches are 100% tested to verify both mechanical and electrical switching performance.
What are signs the clutch safety switch may be failing?
Possible signs include a no-crank or intermittent-crank condition with the clutch pressed, or cruise control that won't set or release as expected. Other faults can cause these, so diagnose first.
