The RF 15N pushbutton enables a very low installation height of 6.2 mm. The overall height can be varied by means of extension plungers, which are inserted into the cross-shaped recess of the pressure piece.
Up to a height of 10 mm (i.e. without or with the small plunger), LEDs can only be placed separately on the PCB next to the buttons. From a height of 12 mm, a maximum of 2 LEDs can also be inserted into recesses in the pushbutton housing. In order to achieve satisfactory illumination, the LEDs should be placed on LED distance sockets from a height of 12.5 mm.
