I'm looking for a 12 volt relay that has a delayed off capability.

This relay is for use on a car. When the ignition is turned on the relay will switch on a small instrument cooling (one amp) fan. The fan will run continuously as long as the engine is running. When the ignition is turned off the fan will continue to run for about 30 minutes. Then the relay will return to normal of position.

Can you help?

Thanks,

Arthur Mitchell

Do a search for off delay timer on Google.
