Well, there are many kinds of Happ sticks, but we basically only pay attention to four of them. While there are undoubatably more Sanwas than I know about, we pretty much only see three here.
The lever switch JLW, it’s almost like Sanwa made a super.
The ever popular JLF, which has its microswitches on a removable PCB.
And the Flash which is exactly like a JLF except that it uses a different PCB with diodes or whatever of it.
I think the JLW is a bat only, while the JLF can use the same bat with an adaptor. They are smaller bats than Happ.
The 30mm buttons are a little wider than Comps, but have a lower profile. The pressable surface is significantly wider than Comps. These pics should be a decent comparison.
There is no click with Sanwa buttons either. They are very sensitive.
