Artemide Tolomeo switch replacement

Introduction

After a few thousand switching operations, the switch of a Tolomeo may no longer function properly. The unit of switch and lamp holder is available from Artemide as a spare part. These instructions show you how to replace it.

Never forget to disconnect the power plug before starting repairs.

Lift the flanged edge of the lampshade out of the clamp.
Remove the lampshade.

The socket is fixed at the top with a wide ring. This ring is secured against unscrewing by a small brass catch.
Press the brass catch with a small flat-blade screwdriver about 1 mm toward the center of the socket. Do not bend the brass catch too much.
Depending on the socket, the notch may look different. You may have to push it down.
Then unscrew the wide ring on the lamp socket.

Step 5

The cable is secured by a strain relief on the outside. Unscrew the plastic Allen screw until the cable is loose.

Replace the unit.

Step 8

Here is a picture of the switch. You can buy the complete set quite expensive from Artemide, because the socket has been machined by hand. This has the advantage that you can also renew the socket.
You may also find the switch on its own, which is cheaper. It is a snap-in rocker switch with screw connection. The cutout size is 20 x 14 mm, 15 mm installation depth from the frame. The frame is 3 mm high with the dimensions 26x16 mm. This one could fit.

Thanks for the article. When I get to step 5, I don't see an Allen screw. See the linked images. Do you know how I would remove the cable from the socket?
