Solved How could I make a simple switch or relay

You are right. I thought I did this before and got something. So I guess this means I can use hot glue instead of heat shrink.

When did anyone say anything about connecting wires with hot glue?

That's not about connecting wires with hot glue.

No. Ive been soldering wires or whatever together and insulating with heatshrink tubing. Heatshrink is not a connector and I dont always trust butt connectors or wire nuts. Heatshrink also doesnt always work for what you are doing so its good to know that hot glue can go on a board or whatever for insulation.

On one plane I got hot glue all over the led strips in the wings and those are the only led strips that Ive had burn out. So I thought that was why, but maybe it was just that brand.

The relay I got on amazon came in and didnt have much help on wiring so I searched the manufacturer pololu.com and found it there. They had a very helpful description and lower price. $10 from $16 on amazon . They also have smaller lighter cheaper mosfet switches. https://www.pololu.com/category/142/rc-switches

Another possibility: hot glue doesn't dissipate heat as quickly as heat shrink would. If you covered your LEDS in hot glue they may have just gotten too hot when they were on and cooked themselves.
