Controls & Buttons parts diagram: 1 control PCB, 2 power button, 3 fizz button, 4 eject button, 5 led indicator, 6 relay, 7 microcontroller. 9 parts in 7 top-level items. — Controls & Buttons parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	Part	Qty	What it does
1	Control PCB	1×	MCU-based board controlling fill valve, solenoid, and pressure release timing.
2	Power Button	1×	Momentary switch powering on the machine and energizing the cartridge piercing solenoid.
3	Fizz Button	1×	Momentary switch triggering a 3-second CO2 injection pulse; press once, twice, or thrice for light/medium/strong carbonation.
4	Eject Button	1×	Momentary switch venting pressure and unlocking the bottle collar.
5	Led Indicator	2×	Status lights
6	Relay	2×	Electromechanical switch in which a small coil current closes or opens contacts rated for a much larger load, isolating control circuits from what they switch.
7	Microcontroller	1×	Single-chip microcontroller combining a processor core, flash memory, RAM, and peripherals such as timers, ADCs, and serial ports to run the device's control firmware.
