    Hi,

    Im just starting out a new project making engine pre-heaters for RC nitro engines but would like to include some sort of timed switch to stop things getting to hot if left unattended.

    Ive done a google search to see if there is any sort of timed switch available but have come up emtpy. What I need is a switch which will run of 12V DC and turn off after 5 mins, ive read you can do this with a circuit but need some help..

    Thanks

    John

    A google search turned up empty? Are you sure you spelled google right? ;)

    "12v timer relays" got me 336,000 results...in .42 seconds.

    A 555 timer and a relay will do what you want.
