Relays are electrical switches used to convert a small electrical load into a circuit capable of handling a high amperage load. Computers and small switches are not designed to carry the higher amperage requirement of a circuit that may have an electric motor, solenoid, or high amperage lighting fixture. Within a relay are contacts that are controlled with electromagnetism, when the circuit switch commands the device on or off, magnetism will pull or release the contact arm closing or opening the contacts within the relay that carry the voltage.

Product Features:

• Product constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.
• Computer-Aided Design (CAD), laser scanning and 3D printing – utilizing Fused Deposition Modeling (FDM) and Stereolithography (SLA) – in the part design process ensures speed-to-market and a precise fit guaranteed.
• Where applicable, robust circuit board design increases durability due to heat, shock, and random electro-magnetic pulses (EMP) and power spikes.
• Tin plated lead frame prevents corrosion and ensures a reliable terminal connection under adverse ambient conditions.
• 100% thermo-shock and vibration tested to ensure superior performance in extreme conditions.
• 100% end-of-line tested to ensure accurate signal output providing product reliability, every time.
