I took off existing switch & replaced with this:
TOGGLE SWT -SHORT LEVER TYPE - Carbatec . I just leave permanently on, with the remote switching on & off. Better be politically correct and advise you use a sparky or the safety police will be all over me.
They also have a cover plate:
Replacement Switch - suits many Carbatec machines (56x88mm plate size) | Electrical Switches & Leads - Carbatec . I didn't bother with this, just made one up.
My dusty cord runs out of the cabinet into a powerpoint fitted with one of these:
Arlec Remote Controlled Power Outlet - Twin Pack | Bunnings Warehouse I have a different type but essentially the same. They work really well, and I think they would still work if powerpoint was in the cabinet, but not 100% sure. The big green shed sells them singularly and other various pack quantities. They may be a bit cheaper on amazon, not sure. Anyway, really recommend having the remote if dusty is in cabinet or externally located. Makes life very easy & I think these units work up to around 30m, not requiring line of sight, but please check the model before purchase. Hope that helps.
