Standard Ignition LX-351 Ignition Hall Effect Switch

Ignition Hall Effect Switch for Distributor Applications

Standard Ignition LX-351 is an ignition hall effect switch designed for distributor-mounted electronic ignition systems. It uses copper windings, permanent magnets, and high-temperature enameled wire to support a strong signal and stable electrical performance in demanding under-hood conditions.

Built for select Chevrolet, GMC, Buick, Oldsmobile, and Pontiac applications, this LX-351 ignition hall effect switch is a direct-fit service part for distributor-based ignition repair. It is a practical replacement when diagnosing signal loss, intermittent spark, or distributor pickup issues on vehicles such as the Chevrolet S10 and GMC Sonoma.

Key Features

• Distributor-mounted ignition hall effect switch
• Male connector and male blade terminals
• 3-terminal electrical connection
• Copper windings and permanent magnets for signal output
• High-temperature enameled wire for improved insulation
• Standard Ignition LX-351 for OE-style ignition service

Detailed Description

The Standard Ignition LX-351 is engineered for distributor ignition systems that rely on a hall effect signal to trigger ignition timing. Standard Ignition applies electronic ignition experience and in-process quality control from component manufacturing through final assembly, helping maintain consistent electrical performance. This part cross-references Spectra Premium MP132 for the same application.

Compatible With select 1982-1991 vehicles including Chevrolet S10, Chevrolet Astro, Chevrolet S10 Blazer, GMC S15, GMC Safari, GMC S15 Jimmy, GMC Sonoma, Buick Century, Buick Skylark, Chevrolet Camaro, Chevrolet Celebrity, Chevrolet Citation, Oldsmobile Cutlass Ciera, Oldsmobile Omega, Pontiac 6000, Pontiac Firebird, and Pontiac Phoenix. Fitment includes distributor-specific notes such as Dist. No. 1103513, 625 and vacuum-advance or non-vacuum-advance configurations where listed.

What It Helps Fix

• Intermittent ignition trigger signal from the distributor
• No-start condition caused by a failed hall effect switch
• Rough running from inconsistent ignition timing input
• Stalling related to distributor pickup signal loss
• Misfire concerns tied to worn electronic ignition components

Installation Notes and Tips

Verify distributor number, connector style, terminal type, and engine configuration before installation. This LX-351 uses a male connector, male blade terminals, and a 3-terminal layout, so matching the original electrical interface is important for proper operation. Confirm whether the vehicle is equipped with vacuum advance or non-vacuum-advance distributor hardware where noted in the fitment data.

For best results, inspect the distributor cap, rotor, wiring, and related ignition components during service. On applications such as Chevrolet S10 and GMC Sonoma, confirming the distributor identification number helps ensure the correct replacement is selected.

Quality Assurance

Standard Ignition manufactures electronic ignition components with controlled production processes and OE-focused engineering. The LX-351 is built with materials selected for signal strength, insulation performance, and consistent distributor operation.
