Seimitsu remains the second most popular Japanese arcade parts manufacturer largely in part by its high quality micro switches such as the PS-14-D. This microswitch is used in the following 24mm and 30mm buttons:
This microswitch is used in the PS-14-K and DNK 30mm and 24mm buttons respectvely, and provide a slightly stiffer feel than the Sanwa SW-68 microswitch. Those who prefer to confirm their hits in fighting games with a confident tap or those who enjoy their shooters are well aware of the benefits the PS-14-D microswitch provides.
A few of my stock namco microswitches died, and the seimitsu ps-14-g don't quite replicate the feel of namco buttons. Anyone looking to fix their namco buttons, these are perfect replacements. The only caveat is the inability to resolder the switches into the stock namco pcb. Unknown
