Hi! I need to switch on and off 4x(36W @ 220Vac) fluorescent tubes using a rele (solid state ?) or something similar, because I want to light them from a switch and from a push button and from a 24v source (the motor's garage). I know that in the case of just a switch, too much ons and offs will damage it, so I am not sure wich kind of rele should I use, or if there is a circuit for turn the lights on (i.e. a triac that turns on at 0 mains crossing - when to turn it off ?). Any help or idea would be appreciate. Cheers, Diego. -- http://www.piclist.com#nomail Going offline? Don't AutoReply us! email listserv@mitvma.mit.edu with SET PICList DIGEST in the body
