Thank you all so much!
Wow. I feel like a mortal who was allowed to eavesdrop on a debate between the Gods!
I got the reed switches and the 18g. magnet wire in! (The 18 gauge wire will minimize any additional resistance in the circuit and the 1.5A switch will be able to do a lot more than just light a LED!)
I wrapped 14˝ of the the wire around a 7/64˝ drill bit shank (after breaking the first switch wrapping the wire around it—wow, they are fragile!) for 18 turns and it works great! 18 is about all the turns that can fit on the switch, but I figured it really didn’t have to fit entirely on the switch if it wasn’t in contact with it. So . . .
I made two more with 22 turns each and am using them inside the Sun-Mar Excel NE composting toilet to monitor each of the two heating plates separately (WOW!), with the switch sitting inside the coil, which is wrapped with a strip of a rubber jar-opening pad, and all slid inside in a 1/2˝ copper tube to protect them. The ends of the copper tube are sealed with hot-melt glue (a reliably unreliable material which allows it to be disassembled if ever necessary ;-) ).
They work great! Thank you! And the red LEDs are great for night lights! (“It’s a floor wax. No, it’s a desert topping.” ;-) )
Now I want to take a dual trip point temperature sensor with a NTC thermistor, set such that it will switch the heating plates on when the compost inside the composting drum gets down to 20 degreeC point and it will switch the heating plates off when the compost inside the composting drum gets up to 40 degreeC.
But that’s another topic for another time—I still need to do more research. ;-)
Thank you all SO MUCH for your help!
Blessings to you all!
