In MCU-based projects, this design uses a single push button to switch on and switch off 5-V and 15-V supplies in sequence.

Thumbwheel switches offer a straightforward, tactile method for setting numerical values in electronic instruments and control systems.

Switches and push buttons need debouncing. It is straightforward to do this with software, using a library. The advantages of the Switch library are: External pull-up resistors are not required.
