Part 1: Electrical Insert
The main part of the switch, which gets fitted first. Katy Paty’s inserts have their toggles attached – no need to fit a cover at the end.
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).
The connectors on Katy Paty switches are screw fittings, with two slots for each connection (1.5mm and 2.5mm).
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 Katy Paty switches, it is held in place by a small front plate (see part 3), which is then screwed into the insert, securing both parts.
The frame on these switches has not got any moulding at the back to connect it with the insert, which means it just sits like a ring around the insert until it gets fixed with the front plate/screws. This makes the fitting process a bit fiddly – but it’s worth it!
Part 3: Front plate
This last step of fitting the Katy Paty switches requires a bit of patience. The small round front plate is placed over the rocker and onto the frame. A rubber washer sits between front plate and frame to stop the two pieces of porcelain being damaged.
Because neither frame, washer or front plate are fixed yet, they move around freely until the screws are tightened. Keep holding them in place while screwing in the small screws through the front plate into the insert. Unlike our other switch designs, there are no slots or lugs to align the pieces, so you need to check that everything is straight and aligned before tightening the screws completely.
Please make sure not to over-tighten the screws – it can cause cracking of the porcelain front plate.
Removing the switch
With Katy Paty switches you simply need to reverse the fitting process if removal is required. Loosen the two small screws until the whole assembly separates from the insert and remove screws, 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.
