.....from an on/off/on points switch..... I think it was suggested in an earlier post that this switch was suitable to operate the Hornby R8243 points motor. I have never used one of these before so am in the dark as to how they operate but am hoping it's flick left for one direction and flick right for the opposite direction. So, using this switch, is it possible to wire in red and green LEDs to the switch to indicate direction selected? If this is possible is a resistor still required?
