All,
It seems like there have been quite a few people lately asking about the difference in the Happ - lorrenzo (sp?) buttons vs. the Beston Imperial button.
The first and most significant difference is that the Happ buttons come standard with Cherry microswitches while the Betson buttons come with Zippy microswitches. the prevailing opinion is that the Cherry MS is better. Note: you can order the Betson button with the Cherry MS.
Now when it comes to the button construction, I really didn't notice any real differences. Yesterday I recieved an order from Betson and Bob Roberts with buttons so I decided to post a few pictures.
Hope this helps someone...
