Relay switch
Do you want to buy relay switch for your car? if yes, then you are in the right place. Getcarsnow is a platform where you can buy the best and genuine automotive products. Before buying you should have complete guidance of what is relay and switches.
What is a relay switch?
Relays are switches regulated by electrical power, like another switch, computer or control module. The idea of an automotive relay is to automate this power to switch electrical circuits on and off at particular times.

How much does a relay switch cost?
A starter relay can cost anywhere from $20 to $80, while the main relay can cost anywhere from $20 to $200. Before shopping for new parts, check your vehicle’s owner’s manual to ensure that you’re having the exact replacement relay you need.
Types of relay
Latching relay – It is a form of relay that retains its state after being actuated. This is why they’re also known as impulse relays, keep relays, or stay relays
Reed Relay – Reed relays, including electromechanical relays, produce mechanical actuation of physical contacts to open or close circuit paths. These relay contacts, on the other hand, are much smaller and lighter than electromagnetic relays.
Polarized Relay – As the name implies, these relays are extremely sensitive to the current direction. It’s a kind of DC electromagnetic relay with an additional permanent magnetic field source to pass the relay’s armature.
Solid-state relays – Since the control energy needed (to power the control circuit) is much lower than the power to be regulated (switching output) by these relays, their power gain is much higher than electromechanical relays.
Relay and combined sensors
Simple things as temperature supervision relays may exist that for application on the evaluation of temperature in solid, liquid or gaseous means (for motor protection, monitoring, in general, involving temperature on industrial methods, etc.), whose temperature is captured by the sensor, evaluated by the relay and monitored within pre-configured limits. The output relay is turned on or off on the value of the reference, depending on the adjustments on the device parameters. There may be relays via PC connection or via Profibus DP, Asi, Foundation Fieldbus/Modbus, with diagnostics capability, for electronic protection and control of motors, and so on. Other families focused on safety as the flame-detecting relay, which uses ionization or photo-resistor sensors.
