The 3.14.100.001/0000 is a non-illuminated Short-travel Keyswitch with gold-plated contact terminals, 1NO contact and transparent lens. The RF15 series keyswitch features soldering into PCB mounting and snap-action contact system. The low-profile keyboards with RF15 components should be designed with a 19.05mm grid. With this grid, frame webs remain free between the individual keys. The overlay can be glued onto these frame webs; we recommend area embossing over the keys for the overlays.
