Sanwa no longer produces the OBSN-RG series, However, they still make OBSF-RG buttons.  We have a variety of colors to choose from in the OBSF-RG series. 

Sanwa RG Series Pushbuttons are the juggernauts of arcade button hardware. While your standard Sanwa SW-68 micro switches found on non-RG OBSN, OBSF, and OBSC buttons are rated at ~1 million presses, the switch on the RG buttons is rated between 10 and 50 million presses! This means that the life expectancy of RG buttons is 10-50 times longer than other Sanwa buttons.

The OBSN-RG is a screw-in type pushbutton ideal for mounting in thicker arcade and fightstick panels but can be used in any thickness of panel up to 13mm.
