Timer switches: literally just a clock and a switch

@TechConnectify Oof… must resist urge to go on rant about these.
@FinnleyDolfin @TechConnectify im not an electrician by any stretch, but I thought wall switches usually go to some length to prevent arcing as you turn them on or off… the distances in some of these don’t appear to consider that?

@TechConnectify @jason my problem with these is both the mechanical and digital versions emit some noise. The mechanical ones have some constant grinding/chewing sound. The digital ones have a constant high pitch warble. Both drive me crazy.

To your point, I’m sure as long as they have the UL logo on there it’s safe. But who knows when ordering online these days.
