Frequently Asked Questions

Why are longer springs desired?

Longer springs result in a flatter (or slower) force curve. This means that with a long spring, your finger will feel almost the same amount of force throughout the entire keypress.

For example, let's say we have a switch containing an average 14mm spring that bottoms out at 60g. The actuation force for this switch may be around 50g. If we then spring swap this switch with a 22mm spring that also bottoms out at 60g, the actuation force may now be 55g instead of 50g. Therefore, this spring swap has flattened the curve / slope. For the more graph-oriented learners, we drew this up:

Force Curve Example

Due to the above information, these extra-long springs may end up feeling heavier than what you're used to. We typically recommend ordering 5-10g lighter than your preferred 14mm weight.

A longer spring also results in a much snappier return. For a more in-depth read, check out A Beginner’s Guide to Force Curves, written by ThereminGoat.

What is the difference between Two-Stage and Three-Stage springs?

Longer springs have a tendency to buckle when compressed. That's why our Longboi Springs are segmented into multiple stages to help with this instability. In theory, our Three-Stage springs should provide even greater stability than the Two-Stage springs, but it all comes down to preference in the end.

For Two-Stage springs, it is recommended to lube the center segmentation coil with thicker lube (such as 205g0). This is to prevent a spring crunching noise, which can happen with certain switches when the spring compresses and rubs against the switch housing's center pole. Three-Stage springs avoid this situation altogether, since there are two segmentation coils equidistant to the center.

What do the spring weights mean?

These represent bottom out weights - the amount of force exerted while the spring is fully depressed within the switch.

Our spring weights have a rated tolerance of +/- 3g. The actual tolerance is often tighter than this; however, we aim to be honest with our product descriptions and not upsell tolerances that aren't true 100% of the time.

So what spring weight should I buy?

This is very much dependent on your preference. We highly suggest purchasing 5-10g lighter than your usual spring weight preference. You'll find that our Longboi Springs have an extremely flat curve, even when compared to other extra-long springs. This means that the spring will likely feel heavier than what you're used to at the same bottom-out weight.

If you're newer to the hobby and aren't sure what your preference is yet, we recommend going with 53g or 58g springs, since these will feel a bit more similar to most stock springs, in terms of weight.

What is carbon steel wire?

Carbon steel wire, also known as music wire, has fantastic memory properties and is a stronger material than stainless steel. This means your spring will retain its shape and resilience for a very long time.

What causes the spring color to be almost black?

These springs are anti-corrosion plated, which results in a darker-colored finish. This high-quality plating easily passes the salt spray test.

How do I untangle the springs?

Springs often get tangled in bags. Please exercise caution when untangling. Do NOT pull the springs apart forcefully. Instead, turn them carefully until they loosen from one another.

How do I get rid of the spring crunching noise?

With certain switches, these long springs may rub against the center pole area of the housing. We recommend lubing any segmentation sections of the spring with thicker lube (such as 205g0) to reduce friction here.

Should I lube these springs?

Yes, we recommend lubing all springs. We prefer applying Krytox 205g0 to the ends and the center segmentation sections of each spring, but bag lubing with Krytox 105 Oil works as well.

Please note that for Two-Stage springs, we recommend lubing the spring's center segmentation coil with a thicker lube to avoid any unwanted noise from it rubbing against the switch housing's center pole.

Which side should face up?

Doesn't matter. These springs are symmetrical, so both sides are identical.
