pushbuttons microswitch 15A or 0.1A ?

While in the end it may not really matter...
But you should use the correct button for your application. 0.1A buttons usually have gold plating to resist corrosion. 15A buttons usually don't have gold and have tin or silver or such. These are more prone to corrosion, and thus expect a higher current to 'clean' the contacts due to arcing during the contact. So using a high rated switch (contact) with low amperage usage can build up corrosion and lead to shorter than expected life span as it never gets 'cleaned', compared to a switch designed for low amperage usage (which combats the buildup with gold contacts).
But perhaps the amount of usage seen in a MAME machine makes the decision inconsequential. :dunno Just trying to help everyone understand the real point of the contact rating methodology.

High current contacts should be tungsten shouldn't they?
