Illuminated mushroom pushbuttons
Illuminated mushroom pushbuttons are used to actuate contact modules and can also
function as display devices by means of an LED module. Their large, easily accessible
button surface makes them easy to operate with the whole palm of the hand. By pressing or
pulling these buttons, it is possible to generate up to 3 signals with just a single device.
They are available with actuators with a diameter of 30 mm, 40 mm or 60 mm.
Illuminated pushbuttons are available in different variants according to the following features:
● Collar and front ring material
● Color of actuators
● Switching functions: latching / momentary contact
● Switch positions: 2 (all illuminated mushroom pushbuttons) or 3 positions (only
illuminated mushroom pushbuttons with 40 mm diameter)
● Illumination
For further information, refer to Chapter "Mounting (Page 109)".
