Easy Point Position Indicator
This modification can be used to switch indicator lights on and off on a mimic panel to indicate which way a set of points is set, or it could be used to operate an accessory on a DC / Analogue layout.
How it’s done
This points indicator uses a small two-way switch attached to the base of a Peco points motor.
- Step 1. Cut the point operating rod flush with the motor base. (on the side NOT changing the points)
- Step 2. Drill a hole of the same diameter as the rod in the switch. Not too deep or you may destroy the electrical bits.
- Step 3. Check the switching action is OK then attach switch with small plastic ties.
This modification puts a bit more strain on the motor, but my point works OK as I have a slightly higher power supply. A system using a CDU unit would probably be OK.
The switch came from Maplins, but are available from advertisers in the modelling publications, or the well-known on-line auction site.
(This mod came about as I had a double slip which developed a problem in not latching one way. I didn’t fancy replacing it as it would be major surgery on my layout. I used the switch purely as a latch but the idea of using it as an indicator came later)

this is a genius idea! will be trying this modification when using insulfrog points , they can be wired then to throw the polarity making a better contact instead of relying on the point blades!
Electrics in general and points i particular are a bugbear of mine, so I’m very interested to read this.
Your idea is excellent – it could also be used for LEDs used on the mimic board to indicate route. I use Gaugemaster BPDCC80 DCC Autofrog on my layouts. Why you may ask – they are something you can fit and forget. Also even if the point is set against the locomotive you won’t get a short – BUT – the locomotive may derail.
Really enjoyed your article, very helpful and informative.
