hello 2 All What can switch on and off Neon HV? i think it's 20Kv 5-10ma. common relay can't do it cause the contact to close so spark can "jump". Any silicon transistor/scr/triac can do that? Any ideas? Regards Tal Bejerano AMC - ISRAEL -- http://www.piclist.com#nomail Going offline? Don't AutoReply us! email listserv@mitvma.mit.edu with SET PICList DIGEST in the body
