You're looking for a Cherry MX Clear!
Clear switches are tactile switches with a medium actuation force of 55g. The Clear has a pretty tactile bump size which means it has the most friction of all the switches. The switch may feel tiring to some typists due to it's resistance when you hit the tactile bump, but it has been said that it would be beneficial to your fingers in the long term due to it's high resistance cushions helping you to avoid bottoming out.
It's a matter of preference in the end though
Keep in mind that there are more switches out there then the Cherry MX brand.For example: Gaterons, Kaillh, Matias, Topre etc. Please do look at more than just the Cherry brand before buying one. It's worth checking out the differences.
