Which External Switch?

I tried searching for an answer before posting.

If I wire an external switch such as this installation:

[Blockierte Grafik: https://shelly.cloud/wp-content/uploads/2020/06/DC_4xWhite_led_strip_shelly.png]

1) Can the RGBW2 still switch the LEDs on and off despite the switch position?

2) Which type of switch is best suited for this application? The user guide isn't too helpful

Thanks!
