Universal 12V heated rear window timer relay that uses an electronic delay circuit to keep the relay energised for 10 minutes from activation. Use with a momentary switch to start the timer and turn the heater on. The ACC connection to terminal 4 ensures that the heater cannot be used without the ignition on.

Note: Pressing the momentary switch again will turn the relay output off if you want to cancel it before the 10 minutes timer expires.

I wired it as shown on the diagram. Plugged it in and turned it on. The rear window defroster warmed up. Stayed on for about 13 minutes which caused the "on" light to get really hot, but other than that no issues.

I did need to buy like 5 but there ewere just 3 in stock. That means that I have to place another order and pay again for transport.

Good website, fast service

I found the website from a Giogle search, making it easy to do business. The website is logically laid out, although a little more information about the individual products would be useful. The payment process was straight forward and the delivery quite fast.

Simple but effective

Purchased this to power a heated seat mat instead of a rear screen demister. Simple to install and does exactly what it says on the tin. Switches on and off with a press of a momentary switch and switches itself off after approx 10 minutes. A little taller than a standard relay. Standard pin positions so fits relay holders. And not too heavy a price to boot.

Overall extremely happy with the purchase.

Perfect for the job

Fast delivery, excellent price. I would have expected a schematic diagram, but a visit to your technical web site is all that is required

Very Relayable

I used to peer through a fog, never knowing quite where I was going but since this relay came into my life, the view ahead is clear. It makes me feel safe and I bask daily in the warmth of my heated windscreen. Yes readers, I love my relay.
