Standard Ignition DS-838 Door Jamb Switch

Door Jamb Switch for Ford B-Pillar Applications

The Standard Ignition DS-838 is a direct-mount door jamb switch built for Ford trucks and SUVs that use a B-pillar-mounted door switch. It uses copper alloy conductors for strong electrical conductivity and low resistive loss, with a black body, brass and rubber finish, and a 3-blade terminal layout for a secure electrical connection.

Compatible With 1992-1997 Ford F-250, 1992-1997 Ford F-350, 1992-1996 Ford F-150, and 1994-1996 Ford Bronco B-pillar switch locations. The DS-838 is also a direct replacement for 1993 Ford Bronco front B-pillar applications.

Detailed Product Overview

Standard Ignition DS-838 is engineered for door-activated electrical signaling at the jamb location, where the switch responds when the door opens or closes. In Ford F-150, Ford F-250, Ford F-350, and Ford Bronco B-pillar applications, this switch helps restore proper circuit operation for interior lighting and related door-triggered functions. The part number DS-838 is built to meet service demands with materials selected for consistent mechanical action and electrical switching performance.

This part cross-references 1S1307 and DJ39 for the same application.

Common Issues This Part Can Address

• Interior lights that stay on after the door closes
• Dome light operation that does not respond to door opening
• Intermittent door-activated electrical signals
• Worn or damaged B-pillar door switch contacts
• Faulty switch response in Ford truck and Bronco door jamb locations

Installation Notes and Tips

Install the DS-838 at the door jamb or B-pillar location specified by the vehicle application. Verify the connector style, terminal count, and mounting style before installation, and inspect the door striker area for wear or misalignment that could affect switch operation. Confirm the circuit functions correctly after installation by checking door-open and door-closed response.

Quality Assurance

Standard Ignition states that this switch is 100% tested for mechanical and electrical switching performance. The design uses robust materials and copper alloy conductors to support reliable operation in service applications.
