following photos are showing how I changed the buttons for Anywhere MX 2's mouse. This mouse has been with me for 5 years, and this is the second replacement with the left click. The above micro clickers. They are all Omron's. The right tows are about $1 each. The left is $1 for ten pcs.

a replacement D2FC Omron's switch is not as the same feeling as the originals. The DC2FC-F-7N was the replacement of the original clicker

The original switch is D2FCF-7N (10M). 10M is for 10 million clicks before the switch becomes non-functional

the replace, first remove the old switch. I cut up the switch leaving three prongs, then remove each prong each. Finally, use solder pump to remove solder from holes in the circuit board

new switch D2F-01 in place

comparison between D2F-01 (made in Japan) and D2FC-F (made in China). These switches have been in operation over a year. The clicking feel is very much the same as the originals.
