SKU CH-S1XX-FQ7C1

Transparent linear switches with 4 mm total travel, 2.0 mm pre-travel and 55 g actuation force for smooth, consistent keystrokes

  • Smooth linear feel with consistent 55g actuation force
  • Fully transparent polycarbonate housing for vibrant RGB shine
  • Gold alloy contacts plus gold-plated spring resist corrosion
  • Rated for over 50 million keystrokes for lasting reliability
  • 4mm total travel with 2mm pre-travel for precise input

Transparent Linear Switches

These fully transparent linear switches use polycarbonate housings and stems to create a smooth, consistent keystroke from top to bottom. Gold alloy contacts and a stainless steel spring with gold plating provide extra durability for extended use. The 5-pin design fits standard hot-swappable mechanical keyboards. Three actuation weights and three pack sizes are available to match different typing preferences.

Compatibility Check

Verify that your keyboard PCB supports 5-pin MX-style switches before ordering. Ensure the plate cut-outs accommodate the additional plastic legs found on 5-pin models. Confirm the operating voltage of your board does not exceed 12 V AC/DC and that current draw stays within 10 mA per switch. The pretravel of 2.0 mm and total travel of 4 mm should match your desired key feel.

Ideal Users

Keyboard enthusiasts who want a transparent aesthetic with smooth linear action and long lifespan will appreciate these switches. Builders needing clicky or tactile feedback should look elsewhere, as the design is purely linear. Users requiring actuation forces outside the 55 g, 62 g or 67 g options cannot be accommodated by this product.

Questions about this item

Does the pack include only the switches or are keycaps and a switch puller supplied?

Only the linear switches are included; keycaps and a switch puller must be purchased separately.

Which actuation force should I choose among 55g, 62g and 67g?

The 55g option gives the lightest press, 62g adds moderate resistance, and 67g provides the firmest feel for heavier typing preference.

What does the 4 mm total travel mean for daily typing?

The switch travels a full 4 mm before bottom-out, giving a longer, smooth linear stroke with consistent 55 g resistance throughout.
