Part 1: Electrical Insert
The main part of the switch, which gets fitted first. Wire the connectors at the back of the unit to the existing electrical installation and then screw the unit into the back box with flat-head device screws (to enable the frame to sit flush on top of the unit).
Being an authentic replica product, the connectors on THPG switches are “old-fashioned” screw fittings. The live connector is copper-coloured. THPG’s inserts have their toggles permanently attached, not like rocker switches where the cover gets pushed on at the end.
Part 2: Frame
As usual with European switches, the frame that provides the decorative cover over the insert is not permanently fixed to the unit. In THPG switches, it is held in place by a small front plate (see part 3), which is then screwed into the insert, securing both parts.
Part 3: Front plate
The small round front plate is placed over the round opening in the frame. The last step of fitting the switch is simply screwing the small flat-head screw through the front plate into the insert.
Please make sure not to over-tighten the screw, which can cause deformation or cracking of the front plate.
Removing the switch
With THPG switches you simply need to reverse the fitting process if removal is required. Loosen the small flat head screw until it separates from the insert and remove screw, front plate and frame in one go.
As explained above, the toggle is part of the insert in these types of switches and is not removable. If there is a problem with the toggle itself, the whole insert needs to be replaced.
