Looking for thoughts on switching of AC. I will list some basic parameters. Goals are to achieve a faster switch time and have more cycle rating while also reducing cost. Really, a mechanical relay works perfect other than they have some delays and will eventually wear out. It might be that the mechanical really is what we should stay with but still worth a search.
AC - 5-200hz, .1-1VAC, 500mA, N.C. function (latched when not powered).
