4 - 52 PCB Keyswitches
RF - Short-travel keyswitches
RF 15 R - Short-travel keyswitch
Pict.: with 2 mm LED, red
with 3 mm LED, green
General Data
The round actuator of the RF 15 R keyswitch requires round front panel cut-outs. These make it possible to use a narrow
keyboard grid of only 15.24 mm with sufficiently large frame webs between the individual keys. We recommend area
embossing over the actuators for the overlay.
