These bezels allow recessed mounting of standard toggle switches into a model railroad fascia, so the handles don't catch on your clothes as you walk by. They provide a nice finished appearance as well as adding safety and avoiding the risk of switches accidentally being thrown.
Easily installed by cutting a hole with a 1 5/8" diameter hole saw. I recommend pressing the bezel into the hole (ensure the key in the switch mounting hole is aligned correctly for your intended switch and location), and then adding a few small dabs of hot melt glue or other adhesives at the intersection of the fascia and bezel.
Available in White Strong & Flexible, Black Strong & Flexible, and Metallic Plastic. This is a single bezel, packages of 6 or 12 are also available and are more cost effective.
