Auxiliary Switch for Non-Spring. Belimo S1A
The S1A and S2A auxiliary switches are used to indicate when a desired position of a damper is reached or to interface additional controls for a specific control sequence.
The S1A and S2A auxiliary switches are mounted onto the direct coupled actuator. The switches are modular units that mount directly onto LM, NM, AM, and GM type actuators and are locked into place by guiding grooves on the sides of the actuator.
A driver disk is attached to the actuator clamp and offers direct transmission of the actuator position to the micro switch cams. The switching points can be set over the full scale of 0 to 1 simply by adjusting the slotted discs.
