If you're looking for an AC/DC switch that looks like a standard toggle walls switch I think Eagle Electric/Cooper still makes one.

It's catalog #777 for a single-pole tungsten filament lamp load rated switch (on-off) - 10A 125V "T"; 5A 250V

then there's also #784 and #787 which is 10A 125V; 5A 250V.

Are these the switches that used to go CLICK CLACK when you would turn them on and off? I have these installed at home (they're old though). Mine are Leviton.
