What do YOU use ??

This one, available from jameco
It stands up well to the short 2A pulse, too.
Consult the data sheet - this time the Chinese do not exaggerate, but mind you - the rated current is NOT for continuous duty.
When people use digital input push switches rated 50mA - that sort of foolishness didn't come to my mind, however.

Addendum
Look for SCIparts PB's. Same rating, but less expensive and come in more colors.
Try https://www.rapidonline.com/sci

The part to look for is R13-521X X=Colour e.g. B=black . 0.5A@125V is more than ample for the short 2A pulse@20...40V The resistance is 50mOhms --> metallic tongue contact, not just a flimsy wire type
