We are not electricians but to us this looks like more than a run of the mill light switch. Everything is at least twice the size of the average light switch, maybe a cooker switch or some such thing. In good condition with a couple of scuffs to the ceramic base. There is a small repair to the base (see images) but this is only really visible if you're looking for it, the working bits are undamaged. Complete with all screws etc.
