Will I need an adaptor plate for my 'bakelite' switch?
It really depends on how or what you are fitting them to. You need an adaptor kit if you are fitting our 'bakelite' switch on to an existing wall box. The adaptor plate fits to the wall box and the mounting block is fitted to the adaptor plate by using the long screws through the mounting block from the 'bakelite' switch.
These adaptor plates are pre drilled to fit the single mounting block for our 'bakelite' switches.
Measures 6.5cm x 4cm. metal plate, screws supplied.
