Hi everyone. I need a circuit so that a toggle switch outputs a momentary signal, to use in flight simulation. I found this circuit on a flightsim website. Could anybody tell me if this optocoupler would work with this circuit please. http://www.maplin.co.uk/Module.aspx?ModuleNo=2228&DOY=19m10 He mentions in the article, that if you can not get an AC type, then you need to insert a diode in front of the coupler. If it helps, here is the original article. http://www.flightsim.com/cgi/kds?$=...ction to momentary switch action using relays Thanks in advance for any help. Colaboy.
