Relays and Switches From Custom Truck

Your truck relies on switches and relays for everything from lighting and motor control to activating safety systems and fuel pumps. For reliable performance and long-lasting parts, trust Custom Truck.

Relays

Truck relays are responsible for your vehicle’s electrical functioning. They’re equipped to handle higher current loads to power different parts, including advanced safety features. A relay activates your vehicle’s powertrain, cooling fans, remote controls, starters and more.

Most automotive relays found in standard low-voltage vehicles work via electromagnetism and circuits, with the built-in capability of preventing surges. Their design also lets them perform multiple functions via one input to keep operation seamless and convenient.

Custom Truck carries a wide variety of relays, including:

  • Power
  • Time delay
  • Latching
  • Switches
  • Thermal
  • Signal
  • Micro

As you shop for relays, make sure the one you choose is compatible with your circuit design and meets the right voltage and current ratings for your vehicle.

Switches

Truck switches are a convenient way to control different vehicular systems and operate various functions, like opening and closing automatic windows and locks, adjusting mirror placement and enabling features like traction control.

Custom Truck has you covered with extensive electrical switch options for sale, such as:

  • Toggle
  • Push button
  • Rocker
  • Rotary
  • Battery
  • Combination
  • Function-specific, such as windows or wipers

Make sure the switch you choose is the right fit for your electrical system, including the truck’s voltage and current levels. Look for added bonuses, such as maximum durability or ergonomic features.
