What you're looking for is referred to as a "panel mount pushbutton/momentary" switch. The leads can either be solder lugs (which have wires soldered to them) or "PCB mount" meaning it has two pins to mount to a circuit board. The latter is probably more viable for a commercial device, the former is easier for prototyping. You can find them in a variety of styles with different parameters (usually for things like waterproofing, action force, number of switches, etc). Here is an example: https://www.amazon.com/Momentary-Button-Panel-Mount-Black/dp/B074HBYZL5 https://www.amazon.com/Momentary-Button-Panel-Mount-Black/dp... The keyword to keep in mind is "panel mount."
