Neptronic AC2-T Actuator Auxiliary Switch

The Neptronic AC2-T Actuator Auxiliary Switch is an add-on electrical switching module used to provide position-based auxiliary contact response from motorized damper and valve actuators. It is installed on compatible Neptronic L, T, and R series actuators within HVAC systems where additional on/off signaling is required for part coordination and control logic. The unit operates as an independently mounted component with adjustable switching points, allowing contact activation at defined actuator rotation angles. In application, it is integrated into control assemblies of air handling and ventilation systems, where it supports internal signal switching for monitoring and control operations within equipment.
