Carquest Premium – Multi-Purpose Relay (Part No.RAA1579)

Multi-Purpose Relay

from

$115.99
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.

Carquest Premium – Engine Oil Pressure Switch (Part No.SBA1018)

Engine Oil Pressure Switch

from

$23.99
Carquest Premium Vehicle Solutions line of vehicle electronics are designed for OE form, fit and function for both import and domestic vehicles. The oil pressure switch reports engine oil system pressures to the on-board computer or directly to a dash light, and when oil pressure is low, will notify on-board computers and illuminate the low oil pressure warning light. When not replaced, vehicle operator may not be notified of engine oil pressures falling below critical limits. A failing or improperly functioning oil pressure switch will provide erratic or inaccurate readings to on-board computers, affecting performance and system function. In more advanced vehicles, an improperly functioning oil pressure switch may not notify on-board computers of critical system pressure, thus not allowing the computers to place the vehicle into limp mode to protect the engine.

Product Features:
  • Designed and manufactured with high quality materials, industry leading electronic components and strict quality controls. Engineered to meet or exceed OE performance and to meet the uncompromising demands of service professionals.
  • Direct fit replacement matches proper OE fit, form, and function and ensures trouble free installation of your oil pressure switch.
  • Polyimide film diaphragms offer high temperature performance and enhance life-cycle durability. Oil-resistant O-rings and seals, as well as OE-grade thread-sealant match OE design.
  • From design to manufacturing, the use of proper materials, components and multiple glued seals help prevent oil leaks.
  • All units are 100% tested using advanced end-of-line equipment that pressurize the switch, confirm proper calibration and functionality, and check for leaks to ensure each switch meets manufacturing specifications before packaging.
