Hello from Australia!
Hoping for some help controlling 3x actuators on my camper's roof.
Non have any limit controls and all are operated manually via DPDT 20A switches. So 3 actuators = 3 switches.
Had experience with actuators over running their extended limit and jamming up.
So the design goal is to fit reed switch/magnets at the highest and lowest permitted reach and have reach control by cutting power at the ends - so to speak. Ideally I will end up with one DPDT up-off-down switch that controls all 3 actuators and sends them more or less in unison to the extent of their travel. They do track each other well and this isn't an issue so synching isn't required in any solution.
The diagram here is a start.
The reed switches are 0.5A vs. the actuators 15-20A (12V).
So I need a way to get around this.
Relays driven by reed switches?
Or is there a more elegant way?
Open and grateful for help.
Diagrams are good!
Thanks in advance.
