I’ve got an old light switch, the kind you twist on and off (think of the one in Clara Bow’s apartment in It). “June '98” is stamped on the interior of it, and I presume it isn’t speaking of 19–. Anyway, I’d like to use it to toggle a couple sconces in new library I’m building in the basement. My first thought was to just wire it up and use it as-is, but it isn’t like the push-button switches I’ve used elsewhere that look safe as any modern switch, it really looks rather scary.
Is there any way (I’m sure there is, but any good way) of using the switch to control a low-voltage circuit of some sort that in turn controls the main household circuit with the lamps on it using modern parts to handle the latter?
