Reset switch part number

[ch604]

From the images they appear to be SMD 3x4x2 2 pin pushbuttons, correct?

This component is compatible. Part number is B3U-1000P(M)
(this is just one of many compatible buttons)

Also keep in mind that the reset switch is completely optional, as you can map a keyboard button to reset with QMK and ZMK and you can also enter reset by shorting the GND and RST pads on the micro-controller.

This is the footprint, for reference

Thanks for that pcb breakout and the exact reference part, looks like the piece I selected will fit!
