Installation
THPG toggle switches require a bit more patience to wire up, simply because they are modelled on original designs and don't have the modern conveniences of push-contacts and encapsulated backplates.
Just follow the step-by-step pictures below or go to ourย THPG toggle switch installation page. Like all THPG switches, these have open screw terminals.
NB: We used a European round box in the step-by-step pictures, but the procedure is the same for square UK boxes.
