Wow, that’s got me thinking!
The control module for the Happijacs is in the left rear compartment on my Northern Lite.
I keep the remote in there.
It would be really easy to wire a shutoff switch in the power wire to the module, which would be super convenient to reach when using the jacks.
I’m gonna do that.
Edit: I brought this up on a Northern Lite forum and a guy chimed in saying his did this!
I just now went outside and pulled the power wire off my controller and I’m absolutely going to put on a switch.
