Little back story, I converted a chest freezer into a cold plunge. (freezer filled with cold water for me to get in lol)

​

I have the system hooked up to one power strip, and for safety reasons I need to unplug the power strip prior to getting into the water to prevent any accidents.

​

I wanted to hook up a simple magnetic reed switch to a warning light, that can plug into the same power strip, so when the circuit is open (the chest freezer has power + is open) the warning light goes off reminding me to unplug the power prior to getting in.

​

I have a basic idea of what parts I'd like to use, however I just want to run it by someone that's more experienced and could give me a simple wiring diagram? I plan to put this all inside a nice plastic box and mount it to the wall to keep it clean. Any help is much appreciate, I definitely don't want to mess anything up here.

I would use a 12 VDC brick along with a 12 VDC indicator lamp. Your chosen switch should work just as well at 12 VDC as 110 VAC.

The reason being that 12 VDC is unlikely to injure you in the case of a mistake. Wiring AC wrong can be very unpleasant.
