as above can anyone recommend a place to get the above joystick about 60mm high not very big.
3 position electric proportional joystick

I have this servo stick.
if your wanting electric proportional then you need to know exactly what the output signals or you got no hope of it working.

its an electric one i am after. it's a project i am trying to convert a valve to proportional. i am not sure of the outputs tbh

i won't have enough control i don't think with an on-off type switch.

@Mr Happy
As @Mursal says, big jump from simple on off solenoid control to full blown proportional control. The valves require proportional drive solenoids and electronics are required to control them and provide feedback and positional control. The joysticks etc are the “easy” (cheap) bit! Have fun.

LOVEHONEY should be able to fix you up !
Too complicated. Integrating the optical sensors with voice operating system and calibrating the touch sensitive
receptors can be a nightmare to calibrate, especially if the contact surfaces are not cleaned with alchol first
It all depends what you are trying to do. You don’t need position feedback for all applications. Just a solenoid valve which will work of a PWM signal which you can drive and program via a £20 arduino. Clutch valve on a 40 series sldp works this way. They don’t actually know the position of the solenoid valve, hence why you have to calibrate them every now and then. If it’s for something more critical used in a lifting application, the position control may be required, but again some systems, albeit not very good ones had simple proportional control with no valve position feedback. Matbro TR250 ITL with apitech hydraulics as an example.

Rs components or Farnell sell proportion joysticks but as has been said before that's the easy bit!

If it’s only for sliding a hitch in and out and simple on off will do it, just restrict the flow to the hitch ram to make it move slowly, a lot of John Deere’s are like this
