Features

Application The auxiliary switches are used to signal positions or to execute switching functions in any are used to signal positions or to execute switching functions in any angular position.
Mode of operation A form-fit engagement is created between a driver disc and the spindle clamp (Damper (Damper actuators) or on the position indicator (Rotary actuators), causing the position to be directly , causing the position to be directlytransferred to the trip cams of the microswitches.The switching points can be freely selected within the specified range of rotation by means of a dial. The current switch position can be read at any time.
Installation The 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.
