Once you have hot-swap switches, the cheapest way to totally change how a board feels is a spring swap. Aftermarket springs let you make a light 45g linear feel like a heavy 63g typing switch, or the reverse, without buying new switches, and long or slow springs add a punchier, springier return that stock Cherry springs do not have. This is a genuine enthusiast tweak, not a mainstream one, since it only makes sense if you are already comfortable opening switches. Here is the value pick, lighter and two-stage options, and the gram vocabulary you need.

Top picks at a glance

What should you look for in switch springs for weighting?

A few things separate a good switch springs for weighting from a frustrating one: weight is bottom-out grams, long and slow springs change the return curve, requires full switch disassembly, and sold in packs of about 110. Weigh these before you buy.

• Weight is bottom-out grams: 35g is very light, 62 to 63.5g is medium-heavy, 68g and up is heavy; actuation force is lower than the printed number, so buy by feel target, not the headline.
• Long and slow springs change the return curve: long (about 16mm) is punchier and springier, two-stage or slow is soft-then-firm; stock Cherry is about 15mm.
• Requires full switch disassembly: you need hot-swap or de-soldered switches plus a switch opener, and a full board is 60 to 100-plus switches, so budget real time.
• Sold in packs of about 110 that cover one keyboard; buy an extra pack because springs get lost and pinged during the swap.

Springs, grams, and the tedium

A spring swap is the cheapest transformation available to someone with hot-swap switches, and it works because the spring is the single part that determines how hard you have to press. Every switch has a stem, a housing, and a spring, and swapping only the spring changes the force curve while keeping the smooth linear or tactile character you already like, so you can turn a light 45g linear into a planted 63g typing switch, or lighten a heavy switch for gaming, for the price of a bag of springs rather than a whole new switch set. Two vocabulary points save you from buying the wrong thing. First, spring weight is almost always quoted as the bottom-out force, the grams it takes to fully press the key to the floor, and the actuation force where the keypress actually registers is lower, so a 63.5g spring does not mean 63.5g to type, it means that at the bottom, and you should shop by the feel target you want rather than fixating on the number. Second, length and shape matter as much as weight: a long spring, around 16mm versus the stock 15mm, pre-loads earlier and gives a snappier, more consistent return, while a two-stage or slow spring has a progressive curve that feels soft at first and firmer at the bottom, which some love and others find mushy. The catch, and the reason this is an enthusiast tweak, is labor. There is no shortcut: you open every switch, remove the old spring, drop in the new one, and reassemble, across the sixty to a hundred-plus switches on your board, and springs are tiny and prone to pinging across the room, so buy an extra pack and set aside real time.

What are the best alternatives?

Bottom line: Durock 63.5g long springs are the reliable weighting upgrade, 35g stainless goes feather-light, and the 2-stage springs add a cushioned curve. Learn the bottom-out gram vocabulary before you order. Compare it with our barebones guide and our macro pad guide.
