Are there any 12V relays on the market?
12v Relays available online including heavy duty 12v relays, mini 12v relays and micro 12v relays, 4 pin relays, 5 pin relays and normal open relays.
What are the different terminal numbers for relays?
In addition, the terminal numbering is different, using 1, 2, 3, 4 & 5 instead of 30, 85, 86, 87 & 87a. There are other relay designs that are used for some more complex applications in vehicle systems.
What kind of relay is used for make and break?
There are other contact configurations discussed below but make & break and changeover relays are the most commonly used.
What do I need to know about standard relays?
Please provide some information about the part you are looking for. With more than 225 unique relay categories, Standard and Intermotor are your go-to source for a full line of accessory and electronic relay solutions that match the OE for fit, form, and function.
What kind of relay do I need for my 4×4?
The switch that is installed in the cab of your 4×4 actually only powers the relay itself which draws very little current. In most installations a 30 AMP relay from Radio Shack (Auto Relay Cat. Number 275-226) will do unless your amperage demands exceed 30 amps. I like to used a lighted switch in the cab to let me know if driving lights are on.
How do you connect a light relay to a battery?
Then run a heavy gauge wire from the battery to the relay placing a 30 Amp fuse in line very close to the battery. Do not connect the power to the battery until all wiring is done. Then I run a single heavy gauge wire out to the lights or other accessory.
How many amps does a Radio Shack relay need?
In most installations a 30 AMP relay from Radio Shack (Auto Relay Cat. Number 275-226) will do unless your amperage demands exceed 30 amps. I like to used a lighted switch in the cab to let me know if driving lights are on. The method I use for wiring the lights and other external accessories, for the most part, follows the diagram pictured above.
Do you need a switch to turn on a relay?
In almost every case where high current is required, the switch you will use to turn on the power should not handle the load because most switches are not designed to handle higher amps. The job of switching the power is better left to a relay. What is a relay? A relay is a device that, through a magnetic induction coil, turns on the power for you.
