Farmtek Timer - Light Curtain Switch Ring Upgrade

This is a replacement switch ring for the Farmtek Timer poles.

The originals can get caught and spring off or can be knocked by a dog as it passes the switch which can turn them off !

My design reduces the chance of them being knocked and turning off, and also prevents the ring from coming completely off and being lost as they are secured with a screw to hold them closed.

These require a 6mmx6mm round magnet to be inserted as they activate a reed switch inside the pole to turn them on.
