Longjing S uses a five-pin MX-style mechanical footprint. It is intended for conventional mechanical keyboard PCBs and compatible hot-swap sockets, not Hall Effect or magnetic systems. Check that the PCB accepts five-pin switches because boards designed only around a three-pin footprint may not provide clearance for the two locating pins.
Both force options are factory lubricated.
Longjing S is a conventional 5-pin MX-style mechanical switch, not a Hall Effect switch. A hot-swap keyboard must specifically accept standard five-pin MX-style switches, so check the PCB and socket before ordering. The 10-switch pack suits testing or replacements; the 70-switch pack can cover many compact layouts, but some 75%, TKL and full-size boards need more, so count the actual switch positions first.
Use verified force, travel, mount and lubrication fields to see how this switch differs from nearby alternatives.

CORE EXPERIENCE
Longjing Tea S is a light tactile switch built around a subtle bump and a longer-travel feel.
It is for buyers who want tactile guidance without a large, abrupt event.
Bottom line: A subtle tactile choice with a longer-travel direction.
WHAT MATTERS
The 37gf and 45gf options let buyers choose an easier or slightly firmer press while keeping the product’s restrained tactile character.
Construction facts matter as part of the switch format; they do not predict one fixed sound.
What it means: Choose resistance without changing the subtle-bump intent.
FIVE-PIN FIT
Longjing Tea S uses a five-pin MX-style footprint. Confirm that the PCB and hot-swap socket accept the two locating pins before ordering a tester or full-build pack.
Once fit is confirmed, choose quantity from the board’s actual switch count and any desired spares.
Spec transparency: Verify five-pin fit before planning quantity.
WHO IT SUITS
Choose Longjing Tea S when you want light resistance and a restrained tactile event.
Choose a large-bump tactile for stronger feedback or a linear when uninterrupted travel is the priority.
Build note: A light tactile option for restrained feedback.
Longjing S is a tactile MX-style mechanical switch. Its bump is intentionally light and restrained rather than sharply pronounced. Two operating-force options are offered — 37gf and 45gf — so you can choose a lighter or slightly firmer version within the same five-pin PA66/POM product family.
The difference is force. The 37gf version uses 37±5gf operating, 45±5gf tactile and 43gf bottom-out. The 45gf version uses 45±5gf operating, 52±5gf tactile and 50gf bottom-out.
Choose 37gf if your priority is lower resistance and easier repeated presses. Choose 45gf if you prefer a little more firmness. Both are still light-tactile choices, so neither should be expected to feel like a heavy or aggressively tactile switch.
Yes. Both the 37gf and 45gf Longjing S switches are factory lubricated. They are not hand lubed, and a specific lubricant formula is not published.
Yes. The Longjing S is a five-pin MX-style switch. Check the PCB before ordering because a five-pin switch requires clearance for the two additional plastic locating pins.
It can work in a hot-swap keyboard when the PCB and sockets support standard five-pin MX-style mechanical switches. Hot-swap compatibility belongs to the keyboard system rather than the switch alone, so do not assume every hot-swap board accepts five-pin mounting. This conventional switch is not intended for Hall Effect or magnetic-switch PCBs.
Total travel is 3.7 ± 0.3 mm, and conducting (pre) travel is 2.0 ± 0.3 mm.
Count the switch positions on your exact keyboard layout and add a few spares. The 10-switch pack is useful for testing, macro pads or replacements, while the 70-switch pack can cover many compact builds. Some 65%, 75%, TKL and full-size keyboards need more than 70 switches, so confirm your layout before ordering.
