Switches
Switches are the interface between the driver and vehicle systems. They provide direct control over functions like lighting, wipers, and heating — and must perform reliably in all conditions.

In trucks and heavy-duty vehicles, switches are used constantly. They act as control points between the driver and multiple electrical systems, ranging from basic functions like headlights and fans to more advanced controls for safety features or hydraulic mechanisms.
A quality switch must withstand heavy use and exposure to dust, vibration, moisture, and temperature fluctuations — common in commercial driving environments. Faulty switches can result in malfunctioning systems, electrical resistance, or unexpected failures while driving.
Common applications include:
-
Headlight and lighting switches
-
Wiper and washer switches
-
HVAC (heating/ventilation) control switches
-
Control panels for auxiliary motors or liftgates
-
Multifunction steering column switches
Replacing faulty or worn switches improves system reliability, driving comfort, and operational safety.
