I have built a fighting bot but improvements could be made. I currently use 1 channel to switch spinners on and off and another for self righting. The spinners cannot turn during self righting as they are against the floor so I have to switch them off with one switch and activate self righting with another to avoid the spinner motors burning out and then once self righted reverse both switch positions again. Currently each circuit has a normally off relay (5v from the receiver controlling 24V to load), in an ideal world I would have got a relay that allows one circuit 'on' and the other 'off' and then the opposite when given the signal by the receiver e.g. when a single switch on the remote control is 'off' then circuit A is 'off' and circuit B is 'on', when the remote switch is 'on' circuit A in 'on' and circuit B is 'off' - this would free up a remote channel and also ensure the two circuits can never be closed at the same time - with me so far? anyway turns out that this type of relay does not exist for control by a remote receiver so what I am trying to achieve is the following:

So it's not actually a relay as that suggests one voltage controlling another so what is this illusive gizmo I seek actually called? Can I buy one on Amazon?

I'm trying to avoid going down the route of IF / THEN gates on a separate PCB, the daft thing is that all I want is an electrical version of exactly what the pneumatic actuator does - when powered air goes down one hose and when off goes down another.

Thanks in advance.

What relay or other gizmo do I need to switch between two circuits?

I have built a fighting bot but improvements could be made,. I currently use 1 channel to switch spinners on and off and another for self righting.
