PECO PK-11 Feedback micro switch (on-on) needed please.

I am looking for an ON-ON type switch to fit alongside my PECO PK-11 surface mounted points motors to provide feedback information as to when the points actually change. I have read in one Forum that someone has managed this by butchering a PK-13 switch, but that involves cutting holes in the baseboard, and is not ideal for track that is already fixed.

What I think will work is a simple on-on slider switch with a "peg" small enough to fit through the loop of the none-track side of the point motor. With the "underlay" base provided with the points motor, the height to the base of the loop looks about 5mm, so the switch box cant be more than this. Also it would be better if the connections were sideways to the switch to make wiring up easier.

So has anyone found such a switch?

I think slide switches are probably going to be too stiff for the point motor to operate.

What about a PECO PL-33 enclosed micro-switch (or similar)? Put this on the opposite side of the point to the point motor so that it is operated by the movement of the tie-bar. Or it might be able to go on the non-point side of the motor. It may need some packing underneath to get the switch to the right height.

I have not tried this out, but it seems to be a possibility.

Even better - use a slow action type point motor - they all come with auxilery contacts & will probably be more cost effective (& reliable).
