I have a dashcam in my car and wanted to disconnect it from the power supply when the car is parked for a longer period of time. I didn't want to keep plugging it in and out, so I designed a 90° USB adapter with an on/off switch. Of course you can also use this adapter for other purposes.

I would be very happy about any feedback :)

If you have any problems or suggestions for improvement then please let me know :)
