Detailed Description

Standard Ignition SLS-194 is engineered as an OE-style brake light switch for vehicles that rely on accurate pedal-actuated stoplamp signaling. The design uses high-grade materials and a contact arrangement intended to maintain consistent switching action while limiting electrical wear. Copper alloy conductors support low-resistance current flow, which is important for reliable brake lamp operation and related circuit performance. This part cross-references Standard Motor Products SLS194T and Dorman 1S5069 for the same application.

Use this part number when servicing Chevrolet Astro and Chevrolet Blazer brake light switch concerns, as well as GMC Safari, GMC Jimmy, and related GM platform vehicles. The SLS-194 is also listed for Chevrolet S10 and GMC Sonoma applications, making it a useful replacement for common stoplamp circuit repairs across multiple model lines.

What It Helps Fix

  • Brake lights that do not illuminate when the pedal is pressed
  • Intermittent stoplamp operation
  • Brake lamp switch electrical contact wear
  • Delayed or inconsistent brake signal activation
  • Faults caused by a damaged or worn pedal switch assembly

Installation Notes and Tips

Verify connector style, terminal count, and vehicle application before installation. Confirm the brake pedal switch location and compare the original part to the SLS-194 for terminal layout and housing style. After installation, test brake lamp operation and related switch functions to confirm proper electrical response.

Quality Assurance

Standard Ignition states that this brake light switch is fully tested for both mechanical action and electrical switching performance. The brand also notes complete quality control throughout manufacturing, from component selection to finished product.
