Just when you thought you couldn't add any more custom tuning to your JLF... It's time for the Paradise JLF Actuators.

This is a full set of actuators, so you can try them all.  Please note, anything 1.5 and up is too large for standard JLF microswitches. Designed to take the stock spring or custom Paradise springs, aluminum actuators are a great way to tune that stick perfectly.

Actuators come in 0.5mm increments from 0.5 to 2.0 oversize, red, orange, green, and blue respectively anodized for easy identification.
