This changeover relay operates on a +12V input signal and has an adjustable delay time (either a delay before ON or a delay before OFF) that the user can configure to meet the requirements of their application.

The relay operates in one of two modes:

  • DELAY OFF - a momentary +12V input is given (e.g. from a momentary switch), the relay energises and there is a delay before the relay de-energises. Note: If a continuous rather than momentary input signal is provided, the timer will commence when the signal is removed.
  • DELAY ON - a continuous +12V input is given (e.g. from an ON/OFF switch), there is a delay and then the relay energises (the relay de-energises when the input is removed)

In both modes the delay time is adjustable between 0.5 seconds and 6 hours, making this relay extremely versatile. The adjustment is made by removing the plastic plugs on top of the relay to access the dials beneath. The adjustment settings are shown in the table below:

Terminal No.



+12V input signal


+12V for load (common terminal)




Normally Open (NO) output


Normally Closed (NC) output






Important:  If the intended load draws more than 10A then this relay should not be used to directly switch the load. In this case the output should be used to switch the coil of a secondary relay that has a sufficient current rating and is fitted with a voltage suppression resistor or diode (e.g. P00694). This voltage suppression is important to prevent voltage spikes damaging the timer relay electronics.

Please note that due to the electronics used in this relay it is not possible to use it to switch the negative side of the circuit.

Delay timer

Just what I needed to keep cooling fan running after the compressor turns off. Easy to install even without any instructions. Just wish it was water Proof

Good eyesight needed

All works ok, as described. But how to tell which program you are on it a matter of trial and error as there is no arrow on the miniature dial. Or if there is it's very hard to read.

exactly as describe and very fast shipping

Used these for creating a timed power supply for the aftermarket heated seat pads in our camper so they don't drain the leisure battery.
Easy to wire up (get the Standard Relay Socket and 6.3mm Female Blade Terminals).
You need a small screwdriver to rotate the adjusters and good eyesight to see the cross-head arrow but setting up is easy if you follow 12 Volt Planet's guide.

needed a relay to be switched on by a 'pulse' but to keep the pump running after the first signal, and this does that perfectly. Just think it's a little pricey, but as long as it keeps working, thumbs up.

Low spec

Adjustment dials not robust with very poor markings. Instructions minimal. Binned it and bought a higher quality item from Farnell for a couple of quid more.


We're very sorry to hear that you felt that the relay was not of adequate quality. Please note that we provide a comprehensive user guide on our website that you can download to assist in setting up and using the relay.

Excellent configuration that it plugs into a regular relay wiring harness.

I put together a HD mobile recording system in my vehicle that I wanted to start recording when the ignition was switched on, But, I needed the recorder to remain running for a set time after the ignition was switched off and the key removed & the only way this could be done was by installing a Adjustable Delay Timer Relay with a Delay off timer, On searching the internet I visited Volt Planet's site which had exactly the thing I was looking for, A 12v Adjustable Delay Timer Relay with Delay on & off plus would take much more current than I would be using, this relay was sealed & compact and box shaped just like other 12v vehicle relays, As I had never done anything like this before at my request Volt Planet included a diagram on how to install the relay step by step and with after sales support if & when I may need it, After the relay was installed I found it took me three attempts to set the timer to switch off exactly when I wanted it to. Ok, this 12V 10A Adjustable Delay Timer Relay with Delay On or OFF was somewhat more expensive than the Eastern products that are available to us, But I always bear in mind, You only get what you pay for. Plus when I return to my vehicle I know I am going to find my hard drive full of video images, Not smoke.
