Hello! I'm new to electronics, and this is my first time looking at limit switches (and I must say I don't understand them well at all).
I have a motor which runs on a voltage from -15V to +15V where the exact voltage determines the speed and neg/pos determines forward or reverse. I want to add a limit switch to my circuit (ultimately a pcb) which prevents the voltage from going above +/- 15V but allows the user to change the voltage in the opposite direction. For example, if the user tries to increase the voltage past +15V, it will not allow that but it will allow the user to turn the voltage back down to +14V.
I have no idea what possible designs would be for this. I've found designs which can flip the direction from forward to reverse, but I don't want this...preferably the motor just continues at the +15V speed and is prevented from increasing there but allowed to decrease.
Thanks!
