Switches and senders are how your vehicle's electrical system detects conditions and passes that information along — a switch opens or closes a circuit based on physical input, while a sender translates a measurement like pressure, level, or position into a signal your gauges and modules can read. A faulty one can trigger an inaccurate gauge reading, a warning light that won't go out, or a component that won't activate at all, like a brake light or backup light. Browse replacement switches and senders for cars, trucks, and SUVs to get accurate readings and reliable circuit control back.
