A buy topic for a change. As with many others I have a small collection of loose, single switches unrelated to my keyboard collection (I have switches I don't have keyboards of and keyboards I don't have loose switches of). Here's a list of ones I could do with:
*Alps SKCM/SKCL Green, Brown, Orange, Amber, Neon Green, Cream Damped, Lock
*Alps non-SKCM/SKCL (virtually all of them)
*Cherry non-MX, non-MY
*Futaba clicky switch
*Any Hall effect or magnetic reed switch
*Matias linear
*Gateron other than clear, black and brown
*any NMB Hi-Tek
*TEC/KPT switch
*ITW magnetic valve
*Mitsumi mechanical, full-size or miniature (any non-yellow miniature)
*SMK Alps/Cherry/inverse cross mount
*Omron B3G or cyan B3G-S
*Romer-G
*Razer switch
Let me know if you've got some of these lying around that you can part with!
