I am looking to use vandel resistant switches to switch case fans on and off. However these are momentary switches, so I think I will need a dual coil latching relay. I want to be able to turn on a fan by pressing the momentary action button and switch it off again by pressing the same button. Can one of you guys confirm that this is possible using a relay and perhaps suggest a model from maplin. Thanks in advance!
You wont be able to do that with just one relay, your going to need something like a 'flip-flop' circuit to have the ON/OFF action.
Thanks from the replay acrimonious. I take it I would be able to use just a relay if I where to use a seperate momentary switch to turn off the relay?
Cleaner, I went through this whole ordeal. Check out my thread from a long time ago: http://forums.bit-tech.net/showthread.php?s=&threadid=18684&perpage=20&pagenumber=1 Basically, your going to have to make a circuit using a flipflop IC. Its easy and I know that thread makes it look complicated.
