RF
4 - 48 PCB Keyswitches
RF - Short-travel keyswitches
RF 15 N - Short-travel keyswitch
General Data
The RF 15N keyswitch provides a minimum overall height of 6.2 mm. The overall height can be varied by extension
plungers which are inserted into the cross-like notches on the actuator tops.
LEDs can only be arranged separately next to the keyswitches up to an overall height of 10 mm (i.e. without plunger or
with small plunger).
Keyswitches with overall heights of 12 mm or more can be provided with a maximum of 2 LEDs which are inserted into
the recesses of the keyswitch housing. LEDs of keyswitches with overall heights of 12.5 mm or more should be placed
onto LED spacers in order to obtain satisfactory illumination.
