Operating Principles

The switch functions as a contact relay, closing the circuit when the vehicle’s reverse gear is engaged. The internal mechanism is triggered by a mechanical linkage or electronic signal from the reverse gear sensor, depending on the vehicle’s design.

• Mechanical Activation: A lever or cam moves the switch contacts into contact with each other when reverse is selected.
• Electronic Activation: An input voltage pulse from a microcontroller or ECU triggers an internal transistor that completes the circuit.

Maintenance & Longevity

Due to its solid construction and low‑wear contacts, the VEMO V52-73-0013 requires minimal maintenance. However, periodic inspections are recommended:

• Visual Check: Inspect for signs of corrosion or mechanical damage.
• Electrical Test: Use a multimeter to verify continuity and contact resistance within specified limits.
• Cleaning: Gently wipe the exterior with a dry cloth; avoid abrasive materials that could scratch the housing.
