I am building a small/miniature electrical cylinder which will be used in scale models, the dimensions of the cylinder(s) are .5" diameter by 3" stroke. A small micro gear motor in the cylinder will be rotating a lead screw which will then extend the piston/ram, the gear motor will be proportionally controlled via a continuous rotation RC servo board (cheap form of a speed controller). My issue is that I don't know how or what I can use as a limit switch to stop the ram once it has reached its stroke, my obvious constraint is size and I want it to still look like a ram. Could I use a membrane pot on the inside wall of the cylinder? Any thoughts ideas etc would be very much appreciated. Thanks
