What Is a Cooker Switch?
A cooker switch is a 45-amp double pole switch used to isolate a cooker or other high-power kitchen appliance. We stock three types, all rated at 45 amps: a single plate switch, a vertical double plate switch, and a horizontal double plate combining a 45A switch with a 13A socket.
What are the three types of cooker switch?
Single plate 45A switch: just the isolation switch, on its own plate, with no additional socket.
Vertical double plate 45A switch: two 45A switch positions on a single vertical plate — useful where you need to isolate more than one high-power appliance from the same location.
Horizontal double plate with 13A socket: combines a 45A cooker switch with a standard 13A socket on the same horizontal plate — useful for a kitchen worktop where you want both appliance isolation and a general-purpose socket in one fitting.
Why does a cooker need a dedicated switch?
Cookers draw considerably more current than a standard socket is rated for, which is why they're wired directly into the electrics via a dedicated 45A double pole switch rather than plugged into a normal socket. The double pole design ensures both live and neutral are fully isolated when switched off — important given the power involved.
Where should a cooker switch be positioned?
Cooker switches are typically mounted on the wall directly above or beside the cooker position, at a height that's easily accessible but out of the way of everyday worktop use. For back box depth, see our back box guide — cooker switches need a 32mm standard back box, though we'd recommend a deeper box where possible for easier installation.
