Technical Specifications

Installation Guide

The V42-73-0005 is engineered for straightforward installation. Follow these steps to ensure proper function:

1. Locate the Brake Pedal Assembly: Identify the area where the pedal contacts the switch mechanism.
2. Mount the Switch: Secure the switch housing onto the pedal using the provided screws or snap‑fit brackets. Ensure it aligns with the pedal’s travel path.
