Selector switches
The selector switch is an actuator with 2 or 3 switch positions. Thanks to the rotary actuation,
up to 3 contact modules can be operated with momentary contact or latching operation. The
fiber-optic conductor integrated into the actuator can be illuminated using an LED module.
Selector switches are available in different variants according to the following features:
●
Actuators (short / long selector or rotary knob)
●
Switch positions
●
Collar and front ring material
●
Color of actuators
●
Switching functions: latching / momentary contact

In the delivery state, selector switches are equipped with two pressure plates

Typical diagram
Each pressure plate can be individually removed and reinstalled. A pressure plate always
actuates the contact modules mounted on the holder at position 3/6 (center position), and
the corresponding outer contact modules at position 1/4 or 2/5.
If a pressure plate is not used, only the corresponding outer contact at position 1/4 or 2/5 is
actuated.
Note about installation of LED modules: The pressure plates must be removed before the
LED module is installed.
