Looking for some helpful advice in selecting replacement Cherry micro switches for replacements in WMS 90's games.
The Cherry part number for the original switches was DA3C-B1AA. Unfortunately these are no longer available. The tech details for these switches were as follows...
Switch Series - DA3C-B1AA
EN Rating - 0.1(0.5A) 50VAC
UL Rating - 0.1A 125VAC
VDE Min Ops - 50,000
UL Min Ops - 100,000
Max Operating Force (gms) - 90gms
The question I have is the operating force figure. I've seen it written elsewhere that this figure is the force required to operate the switch contacts. However when you read the above information, taken directly from the Cherry catalogue, it states as I've copied above "Maximum Operating Force".
The full catalogue can be found here...
Here in Australia, I've been able to locate a DB3C-B1AA switch, which has a Max Operating Force of 150gms. I've seen other restorers here on Pinside use that same switch in their restorations. However Pinball Life offers the DB5C-B1AA switch, which is rated at 70gms.
Has anyone had any experience with the various types of these switches? Can I use a switch with a higher operating force rating and be assured the switch is going to operate each and every time when installed in the game?
