Tronic Single Galvanised Iron Electrical Switch Box, 3 Way

Our review

This is a single galvanised iron box built to hold a three-way switching arrangement, and it is meant to be buried inside a wall rather than surface-mounted. That single detail shapes everything about the purchase. Because it is a recessed box, the wall has to be chased or chiselled out first, so it suits someone already doing that work, whether a working electrician, a contractor on a build, or a competent DIYer renovating a room. If you are not prepared to cut into masonry, a surface-mounted box will save you a lot of effort. Before buying, confirm the box matches the depth and cutout your wall can take, that three-way switching is genuinely what your circuit needs, and that the galvanised finish suits the damp or bare conditions behind the plaster. Compare it with plastic boxes, which are lighter and cheaper but less rugged, and with deeper metal boxes if your wiring needs more room. Available on Sokonia.
