What current will that take?
I've got an old dryer-timer I was thinking of using for something like this...

Hi. Please be very careful with the load current as the fan timer only suitable for load below 2A with 240VAC.

@sagutric please tell me from where you get this timer...i can only find washing machine timer with only 15 minutes...what do you mean by salvage fan? I cant find out on google...From which type of shops i can get this timer? please reply...thanx...

You could user a higher current relay .

Yes thanks, my timer is different though.

The timer used here isn't made to handle much current. The one I have is only rated for 2 amps, but you could use a relay with it to switch whatever load you want.
The timer you have may not be rated for mains switching, in which case you would need a relay and low voltage transformer to power it. If it is mains rated, it should have the max current marked on it.

Thanks for your reply. The timer I have is from an old dryer, it switches mains to the motor and heater (or it did).

I would have though a cloths dryer timer would use relays to control the load to the motor, and heating element. Than again the timer are robust enough to handle 30 amps, I really don't know for sure.

lemonie in reply to staticMay 30, 2011. 3:43 AM

It's a few amps but not as much as 30.
Think about this: relays are still switches, they've got metal contacts. The timer is just clockwork.

great idea!

although i do have lots of rotary timer salvaged from broken washing machines, they are all below 30 minutes timer, electric fan and air conditioner timers are ideal for longer time needed.

That's a cool one I never tried yet, but one I used to use was the "old" coffee makers with a digital clock on it, but it doesn't have the variable time on it. I can't find a picture of it, but it was an old one that was cream color, and the clock was a "modular" box that stood on the side of the maker, and it was a universal clock, that had extra stuff the coffee maker never used, like sleep. Sleep could be set for 1h or 2h, The alarm could be set to when ever... alot of that stuff, was disabled, but the circuit board had the pads for it, so you just solder wires to it. and, since it had a relay for the heater element, it could handle more amps. I had buttons for seconds, sleep (two hours or 1 hour,) 12/24h, alarm, display test, etc.

like that one, but it had a digital clock on it.

Nice! what fan is this originally from? I don't think I've ever seen one with a timer!

You could use adhesive inkjet transparency film to make the scale for the timer.

I have found duel boxes usefull as well . a pic of my brew belt (heater) thermostat enclosed . I used a digital ch stat and moved the ntc to the end of a short flex .
p.s. you could use a 20mm glass fuse(in a carier) to protect the contacts of the timer .
