Mushroom pushbuttons
Mushroom pushbuttons are used to actuate contact modules. 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.
Mushroom 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 mushroom pushbuttons) or 3 positions (only mushroom
pushbuttons in diameter 40 mm)
For further information, refer to Chapter "Mounting (Page 109)".
