Standard Ignition TW-24 Turn Signal Switch

Turn Signal Switch for Classic GM Trucks and Vans

The Standard Ignition TW-24 turn signal switch is a new combination switch built for classic Chevrolet and GMC applications from the late 1960s and early 1970s. It uses copper alloy conductors for strong electrical conductivity and is 100% tested for mechanical and electrical switching performance.

Key Features

• Combination switch design for turn signal and related steering column functions
• New replacement part from Standard Ignition
• Male connector with 3 connector cavities
• 16 blade terminals with male terminal gender
• Copper alloy conductors for low-resistance electrical flow
• Displayed design for straightforward identification during service

Detailed Description

Standard Ignition TW-24 is a turn signal switch for service replacement on select Chevrolet Blazer, C10 Suburban, C20 Suburban, K10 Suburban, K20 Suburban, and GMC Jimmy, G15/G1500 Van, G25/G2500 Van, and G35/G3500 Van applications. This TW-24 switch is built with durable materials and tested to verify both switching action and electrical continuity, making it a practical choice for restoring turn signal operation in older GM steering column systems.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Inoperative or intermittent turn signals
• Erratic signal cancellation after a turn
• Electrical contact loss inside the steering column switch
• Broken or worn combination switch functions
• Signal operation issues on classic Chevrolet and GMC trucks and vans

Installation Notes and Tips

Verify connector style, terminal count, and steering column configuration before installation. The TW-24 uses a male connector with blade terminals, so matching the vehicle harness and switch cavity layout is important for proper fitment. Confirm the application against the vehicle year and model, especially on 1967-1972 Chevrolet and GMC platforms.
