Bluetooth with Micro-Switch on Tube Radio. Power on ONLY when pickup selector is activated.

In a recent video, I looked at a schematic for switching on the Bluetooth module in a tube radio, only when the pickup selector is activated. It used the fact that the magic eye tube was switched off when PU was on. I then mentioned that a simpler option would be to simply use a micro-switch to switch on the power to the module, using some form of physical activation when the PU selector is pressed. I decided to give it a try, and got lucky: A perfect fit with the first micro-switch I bought. Enjoy and stay safe.
