OP1 Universal Switch Set: How the PCBs and 14 Switches Work Together

Learn how the OP1 Universal Switch Set pairs two switch PCBs with 14 loose switches, and follow a step-by-step process to install and test your hot-swap setup.
Quick answer
The OP1 Universal Switch Set gives you two switch PCBs and 14 loose mechanical switches so you can build a custom click feel around the OP1's hot-swap sockets. If you already own an OP1, OP1 RGB, or OP1 8k, this is the flexible route: the PCBs hold the switches, and the switches determine weight, sound, and response.
What the two PCBs actually do
A switch PCB is the small board that carries the switch contacts and connects them to the mouse's main circuit. In the OP1 Universal Switch Set, you get two of these boards because each one holds a single switch position. That means one PCB goes in the left-click slot and one in the right-click slot, and the 14 switches in the set are your spares and tuning options.
The universal sockets on these PCBs are what make the set flexible. Instead of being locked to one switch model, the board accepts a wide range of mechanical switches, so you can swap in a different weight or brand later without buying a whole new mouse. The tradeoff is that you handle the switches yourself, so seating them correctly matters more than with a pre-built pack.
Why 14 switches ship with 2 PCBs
You need two switches installed, one per PCB, so the extra 12 are there for experimentation and replacement. Click feel changes with spring weight and housing design, and small differences between individual switches are normal. Having a batch on hand lets you test a few and keep the pair that feels most consistent.
This is also why the set is a better fit for tinkerers than for someone who just wants a single fixed click. If you prefer a ready-sorted pair with a known weight range, a pre-sorted OP1 Switch Pack is the simpler path. If you want to try several feels and keep spares, the universal set earns its place.
Compatibility check before you start
The OP1 Universal Switch Pack is compatible with the OP1, OP1 RGB, and OP1 8k models equipped with mechanical switches. It is not compatible with the OP1we. That single exclusion is the most common compatibility mistake, so confirm your model name before opening the box.
If you own an OP1w 4k, OP1w 4k v2, OP1 8k v2, or another OP1 variant, check the product page for the specific switch pack listing that names your model. Endgame Gear lists per-model compatibility clearly, and matching that list saves you from a set that will not seat properly.
Step-by-step: installing the PCBs and switches
- Confirm your model and power down: Check that your mouse is an OP1, OP1 RGB, or OP1 8k with mechanical switches, then unplug the USB cable and let the mouse sit for a minute. Common mistake: starting on an OP1we, which the universal set does not support. If the model name does not match, stop and pick a compatible switch pack instead.
- Open the mouse and remove the old switch assembly: Follow the OP1 teardown sequence for your model, keeping screws in a tray so none roll away. Lift the existing switch board straight up rather than prying at an angle. Checkpoint: the socket underneath should be clean, with no bent contacts or debris. A bent socket contact is the most common cause of a dead click after reassembly.
- Seat one switch into each PCB: Press a switch into each of the two PCBs until the housing sits flush, with the actuator facing the same direction as the original. Do not force it; if it resists, rotate it 180 degrees and try again. Common mistake: seating the switch crooked, which makes the click feel mushy. Both PCBs should look identical from the side before you continue.
- Install the loaded PCBs into the mouse: Lower each PCB into its slot with even pressure, then refit the screws in a cross pattern so the board sits level. Avoid overtightening, which can distort the PCB and change click feel. Checkpoint: the click should travel smoothly with no scraping or side play. If a click feels stuck, lift the PCB and reseat the switch before screwing down.
- Test before closing the shell: Reconnect the USB cable with the shell still open and click both buttons several times, watching for double-clicks, missed inputs, or a dead side. Swap in a different switch from the 14 if either side feels inconsistent. Common mistake: closing the mouse first and having to reopen it. Only reassemble once both clicks register cleanly and feel even.
- Keep your spare switches organized: Store the remaining switches in a small labeled bag or compartment so you know which ones you already tested and rejected. Note the feel of your installed pair so a future replacement matches. Checkpoint: you should be able to identify your installed weight by feel alone. Spares are only useful if you can find and identify them later.
Product facts
- OP1 Universal Switch Set - 2x Switch PCBs + 14 Switches: The OP1 Universal Switch Set includes 2 switch PCBs and 14 switches, uses universal sockets for a wide range of mechanical switches, and is compatible with the OP1, OP1 RGB, and OP1 8k models with mechanical switches. It is not compatible with the OP1we. You get the board and the switches in one purchase, but you must confirm your model is not an OP1we before installing.
- OP1 Switch Pack - Zippy DF3-P1L0 50-80gf, set of 2: The OP1 Switch Pack with Zippy DF3-P1L0 switches comes as a set of 2 and is rated 50-80gf. It is compatible with OP1, OP1 RGB, OP1w 4k, OP1w 4k v2, OP1 8k, and OP1 8k v2. If you want a sorted, ready-to-install pair with a broad weight range, this pack covers more OP1 models than the universal set.
- OP1 Switch Pack - Huano Silent 20m 50-60gf, Set of 2: The OP1 Switch Pack with Huano Silent 20m switches comes as a set of 2 and is rated 50-60gf. It is compatible with OP1, OP1 RGB, OP1w 4k, OP1w 4k v2, OP1 8k, and OP1 8k v2. A quieter, lighter option if click noise matters, and it fits the same model list as the Zippy pack.
