Baldor Electric Company 402367-2A Auxiliary Switch NO/NC

Baldor Electric Company 402367-2A Auxiliary Switch NO/NC is a compact signaling contact designed to accompany Baldor motor-control equipment. The NO/NC designation means the device provides both a normally open contact and a normally closed contact in a single unit, enabling a secondary circuit to monitor or respond to the state of the primary Baldor device. As an auxiliary switch, it functions as feedback or interlock hardware within control logic, allowing PLCs, relays, or safety circuits to confirm whether the associated drive or starter is energized or deenergized without loading the main power path. When wired into a control circuit, the NO contact closes to indicate a start or run condition, while the NC contact opens to indicate a release or stop condition, providing straightforward sequencing and safety interlock signaling. The 402367-2A unit is intended for integration with Baldor motor-control assemblies and is designed to supply a dedicated signaling path separate from the main power circuit. Typical applications include interlock signaling for motor starters, status feedback for automation systems, and verification of safe shut-down in industrial control setups.
