This spacer is for the hmv rangemaster radio to replace the broken one.It has a separation in the middle of the the spacer to stop the two screws connecting as it needs to be isolated from the chassis when you engage the switch.

How to install:

1: Screw in a 3+ mm screw into the smaller hole
2: Line up the spacer with the original screw for the switch
3: Using pliers to hold the plastic spacer you can screw in the original screw of the unit.

Additional:
I ended up removing the wire it came with from the power pot and used a longer piece and simply wound the wire around the 3mm screw and used a little hot glue.
