Note that there are normally two main types of momentary push button:

1) the "free" ones, that have no outer protection (and that can be thus activated by - say - a slap with a open hand)

2) the "safe" ones, that have an outer rim that prevents the button to be presssed by anything bigger than the actual button diameter (only finger, pencil , etc. will activate it)

There is a third one, sometimes called "mushroom push button" that is of the "free" type, even easier to activate.

once you have chosen the type you want, you will be able to find a similar one by many different manufacturers/retailers.
