I purchased the 265g, 550g, and 1550g springs to use with the Gateron red linear switches on my Keychron Q11 split keyboard. I use this keyboard positioned below the table for ergonomic reasons, and I needed springs that could support the weight of my entire arm resting on the keys. Standard springs (around 70g) weren't sufficient for my needs. Being able to rest my hands on the keyboard without unintentionally pressing keys is essential for relaxing the extensor muscles in my fingers.
These springs fit perfectly in the mentioned switches. Even with the 1550g springs, reassembling the switches after replacing the springs wasn't overly difficult.
Finding the right resistance for you (150, 188, 256g...) can be tricky. Personally, I find the 265g springs ideal for my typing and have installed them on all my alphanumeric keys. Please consider, I have heavy arms and I like a lot of resistance under my fingers, I am not interested in fast typing.
The 550g springs are quite hard, but I might be able to adjust to them with practice. However, the 265g springs are more than sufficient to support the weight of my fingers, hands, and arms when resting, so I don’t see a need to use the 550g springs.
The 1550g springs, in my opinion, are specifically designed to prevent accidental key presses. They are extremely stiff, making them difficult to press—especially with weaker fingers, like the ring finger, when reaching beyond the home row. They are so firm that - I am wondering - prolonged use could risk strain when attempting to press these keys forcefully.
After installing the 265g springs, I experienced some double-typing issues with a couple of keys. However, this is likely unrelated to the springs themselves. By focusing on more deliberate touch-typing movements (using stronger and fuller keystrokes), this problem was resolved.
Overall, these springs contribute to a quieter and more satisfying typing experience on my linear switches. Keypresses feel more "thocky" and subdued, especially when pressing down the keys. The sound of key release (going up) is similarly quiet and no louder than the original switches, which was a pleasant surprise.
I highly recommend these springs for anyone who positions their keyboard below desk level (e.g., on desk trays or with clamps like Smallrig) and wants a more ergonomic, piano-like hand and wrist posture (where the weight of the arm helps pressing the keys with gravity) rather than the traditional horizontal desk setup.
