Removing the front half of the mouse allows us to get to the microswitches for the two primary buttons. EpicGear helpfully mounted the switches into a plastic "cage" of sorts that encloses them and makes them much easier to remove from their sockets. At least, in theory. In practice, using EpicGear's plastic switch remover tool is an exercise in frustration. The tool itself is similar to the keycap-puller included with most Cherry MX-based mechanical keyboards, but the "hooks" on the end of the tool don't grip very well, and the switches are very unwilling to leave their sockets. As a result, it requires an incredible amount of force to actually pull one of the switches.
In a certain light that's a good thing, because it means the switches are securely mounted. Frankly speaking, I don't think many users will be swapping out microswitches all that often. For one, it's a pain, but more to the point, you'll probably either find that you prefer one switch type over the other or that (like me) you simply won't be able to tell the difference at all. I'm pretty sensitive to the differences in mechanical keyboard switches, but the switches that EpicGear included with the Morpha X feel identical to me.
Both types of included clickers are Omron D2F-series switches. The EG Orange "medium" switches bear the extremely common D2FC-F-7N model number, while the EG Purple "pro" switches are marked D2FC-F-K. These purple switches are a newer Omron model, and they're rated for 50 million actuations at a minimum versus "just" 20 million from the orange switches. This seems to be the primary difference between the two switches; the "K" switches have a nominal operating force of 0.6N while the "7N" switches have a nominal operating force of 0.59N. Both switches have a ±0.15N tolerance, making them practically identical in terms of stiffness.
That's not a bad thing, though. As Omron itself points out, most of the world's top gaming mice use some variety of D2F switches. Both switch types feel great, with a well-defined click and rapid reset. It's simply a little puzzling that EpicGear decided to include two essentially-identical types of switches in the box. I will say that it's very cool how the switches are "socketed", so to speak. It makes replacing them very trivial, so if you happen to ruin one of your clickers playing too much Diablo, you can just swap it out and be ready to go again immediately. Lots of mice seem to meet an early death thanks to switch failure, so the Morpha's modularity in this regard could extend its useful life.
