Tronic Single Galvanised Iron Switch Box for Recessed Wall Mounting

Our review

This is a single switch box from Tronic, made from galvanised iron and intended to sit inside a wall rather than on its surface. Because it is a recessed type, fitting it means the wall has to be chased or chiselled out first, so it is best suited to new builds, renovations, or any job where the masonry is still open and can be cut cleanly. It works for electricians and DIY installers planning concealed wiring for a single switch point.
Before buying, confirm the box is the right size and shape for your switch plate and that your wall type can be chased without damaging the structure. Galvanised iron resists rust better than untreated steel, which matters in damp or coastal conditions. Compare it with plastic back boxes, which are easier to cut in but less rigid, and with surface-mounted boxes that avoid wall damage entirely. If your walls are already finished, a surface box may save you a lot of mess.
