  • Low-profile design fits compact keyboards

  • 3-pin gold-plated contacts for hot-swap boards
  • 60 million keystroke rated durability
  • 10-piece set for custom builds

Low Profile 2.0 Switch Set for Custom Keyboards

This set contains ten low-profile mechanical switches built to the 2.0 specification with three gold-plated pins. It is intended for enthusiasts who are building or repairing a compatible hot-swap keyboard that accepts this specific low-profile format.

Choice of Blue Red or Brown Switch Types

Each set provides a single switch type chosen from Low Blue 2.0, Low Brown 2.0 or Low Red 2.0. Blue switches have an operating force of about 65gf and an action stroke of 1.7 plus 0.4 or minus 0.3 mm. Brown switches operate at about 55gf with a 1.7 mm stroke. Red switches operate at about 50gf with a 1.7 mm stroke. All variants share a total travel of about 3.2 mm and a rated lifetime of about 60,000,000 cycles.

Direct Insertion Into Compatible Hot-Swap Sockets

Installation is a simple push-in action because the switches are designed for hot-swap sockets that accept three-pin low-profile 2.0 components. The main difficulty is confirming that the target keyboard supports this exact low-profile standard; the switches will not fit standard MX-style boards or keyboards that require a different low-profile variant. No retail packaging is included, so the switches arrive loose in a bulk pack.

Questions about this item

How many key-presses can each KS-33(BN) switch handle before replacement?

Each Low Profile 2.0 switch is rated for about 60,000,000 actuations, so a full 10-piece set should last through tens of millions of keystrokes per switch.

Which spec hits its limit first during long gaming sessions — actuation force or total travel?

The total travel of about 3.2 mm is reached on every press, while the operating force stays constant at roughly 50 gf for Red, 55 gf for Brown or 65 gf for Blue variants.

Do the gold-plated 3-pin switches run hot or draw extra power when the keyboard is used all day?

The switches are passive mechanical components; they generate no heat of their own and consume no electrical power beyond the keyboard's normal scan current.
