The MARS 92610 is a Single Pole Double Throw auxiliary contact switch designed for use with Millenium Series motors and armatures. HVAC technicians and electrical contractors rely on auxiliary contact switches like this one to monitor and report the status of contactors, motor starters, and relay assemblies. When a main contactor closes, the auxiliary contact switch opens or closes a secondary circuit, allowing control panels, building automation systems, and safety circuits to confirm that a motor or compressor has actually engaged. This kind of feedback loop is essential in commercial HVAC installations, industrial motor control centers, and any system where confirming equipment operation is required for proper sequencing or safety shutoff. The SPDT configuration gives technicians flexibility. It provides both a normally open and a normally closed contact, so the switch can be wired into a circuit that activates on engagement or one that deactivates on engagement, depending on the control logic required. This makes the MARS 92610 a versatile replacement part for service technicians working on rooftop units, air handlers, chillers, or other equipment using Millenium Series components. Using the correct auxiliary contact switch ensures reliable signal transmission, accurate equipment status reporting, and proper protection against overloads or sequencing errors. The MARS 92610 is a direct replacement part that keeps downtime short and restores control circuit function quickly. It is a straightforward, dependable component for any professional working in commercial or light industrial HVAC and electrical applications.
The MARS 92610 auxiliary contact switch delivers SPDT functionality for Millenium Series motors and armatures, giving HVAC and electrical professionals a reliable replacement part for control circuit status monitoring and safety sequencing applications.
