Toggle switches getting damped

[leosam]

Hello everyone,

I'm among the first to get a PiDP11, and mine is running solid for several years now, with Sytse's FPGA implementation. Thanks to Oscar and Sytse for that.

One of the things that are feeling the age are the switches. All of them work fine, but the movement feels damped, as if oil or grease got less fluid inside. The ones which suffer the most are the momentary switches, as the spring has a hard time bringing them back to the original position.

I haven't scoured the forum a lot to check, but has anyone had this problem? What is the best way to fix it?

Best regards,

Leo
