Standard Ignition NS-67 Neutral Safety Switch

Neutral Safety Switch for Ford Trucks and Vans

Standard Ignition NS-67 is a neutral safety switch built for Ford E-Series vans and Ford F-Series trucks from the late 1980s through the mid-1990s. It is engineered for reliable starter interlock and transmission-position signaling in everyday service work.

With a black and gray housing, one male connector, and four female terminals, this NS-67 neutral safety switch is a direct-fit electrical replacement for many Ford applications, including Ford F-150, Ford F-250, and Ford E-350 Econoline models.

Key Features

• Neutral safety switch for automatic transmission start-inhibit circuits
• Black and gray finish with metal and plastic construction
• One male connector with four female terminals
• Copper alloy conductors for strong electrical conductivity and reduced resistance
• 100% tested for mechanical and electrical switching performance
• Built to meet the demands of professional repair environments

Detailed Description

Standard Ignition NS-67 is a service-grade neutral safety switch designed to help restore proper starter engagement and transmission range signaling. The part number NS-67 is backed by Standard Ignition’s focus on durable materials and tested switching performance, making it a practical choice for Ford E-150 Econoline, Ford E-250 Econoline, Ford E-350 Econoline, Ford F-150, Ford F-250, and Ford F-350 applications listed in the fitment data. This part cross-references Standard Motor Products (e.g., NS135, NS6527) for the same application.

What It Helps Fix

• Engine will not crank in Park or Neutral
• Starter engages in the wrong gear position
• Intermittent no-start caused by worn switch contacts
• Transmission range signal issues at the starter circuit
• Electrical switching problems from heat, wear, or contamination

Installation Notes and Tips

• Verify the transmission range and connector style before installation.
• Inspect the harness connector and terminals for corrosion, looseness, or heat damage.
• Confirm proper adjustment after installation so the starter circuit only operates in Park and Neutral.
• Use the vehicle fitment list to match the correct Ford E-Series or F-Series application.

Quality Assurance

Standard Ignition builds this switch with robust materials and copper alloy conductors, then tests each unit for mechanical and electrical function before release. That process supports consistent performance in service applications.
