The current switch position can be read at any time


• InstallationThe auxiliary switches are attached directly to the spindle clamp (Damper actuators) or on the  spindle clamp (Damper actuators) or on theposition indicator (Rotary actuators). The guiding grooves between the housing and the switch  . The guiding grooves between the housing and the switchensure a tightly sealing fit.
