I’ve been thinking about elevate systems as I’ve been redesigning T057’s. I was intending to use an ordinary servo operating one way only (ie the servo pushes it up, but a spring pulls it down, on the basis that if the marker is pushed it is likely to go up). However, looking at Frank’s diagram I think you may be able to combine the operating switch and limit switches.
The important thing is that the up operating switch is combined with the down limit switch. When the servo is central there is a -ve short and the motor doesn’t work. When the servo is operating downwards, it presses on the lower switch and this makes the marker go upwards. There is a lug attached to an arm on the marker mount which will hit the upper switch lever at its limit of movement. This will create a +ve short across the motor so the motor will stop. When the servo is centred the marker will move down a bit until the upper microswitch opens, when it will stop, and the marker will operate normally. The same thing happens in reverse when the down limit is reached. The system relies on the servo and the lug acting on the same switch levers, which might have to be extended.
