Alps switch putting out double characters

[fohat.digs]

I have a keyboard with Alps switches, a Dell AT-101W into which I transplanted orange Alps from an Apple.

It works great and I really like it but 2 of the switches sometimes return double characters from a single key press. The comma "," does it often, perhaps almost half the time, and the "s" does it perhaps 10%-20% of the time.

Any ideas on what might cause it, and/or should i just replace those 2?

Thanks!

Yea the switchplates are getting worn-out and faulty. You can try to clean them with air duster see if that'll help. Most of the time I just replace them.

I'd replace the two switches. It could be some dust in the switch is causing it to chatter. Alps switches are notorious for easily collecting dirt.
