These Gersung GSM-V1623A3 has an operating force of 190g, which is 70g higher than the A2 switches. This helps promote faster return to neutral and arguably a more responsive feeling lever. Installation requires you to screw out the old mircroswitch and put the new one in its place, no soldering is required. The Cool Bear lever comes with the Gersung A3 switches as standard.
Compared to the Omron A5s, these feels stiffer and more snappy during actuation.
