M9300-2 Johnson Controls Auxiliary Switch

Overview

The Johnson Controls M9300-2 is an External Auxiliary Switch Kit designed to provide additional switching capabilities for M9300 and VA9300 Series Electric Non-Spring Return Actuators. This kit features two independently and continuously adjustable Single-Pole Double-Throw (SPDT) switches that facilitate safety interfacing, interlocking sequences, or signaling functions within the selected rotation range of the actuator. The assembly comes complete with a conduit adapter for secure wiring entry and a plastic pointer for clear actuator position indication.
