The Switches
All Infinity panels now use the same toggle switches, part number 1453-00283 shown here:

Prior to January 2025, rack-mounted panels used a different type of switch, part number 1453-00230 shown here:
Removing a Switch
The current 1453-00283 switch can simply be pried out of the panel using your finger.
A small flat-headed screwdriver is required to remove the 1453-00230 switch. The process is illustrated here:
Be careful not to scratch the surface of the panel.

It should pop out with slight effort.

Installing a Switch
The current switch can simply be pressed into the panel with gentle force.
The older switch requires a little more effort. You will notice two pushable tabs on either side of the intercom display after removing a paddle switch.

With the new switch, push the non-tabbed side of the switch into the left side of the display first. Then gently push the right side into the panel, locking the new paddle switch in place.
