Schneider Electric 9007-CO3 Snap Switch With Auxiliary Contact Mount Block

Schneider Electric’s Square D 9007-CO3 Snap Switch with Auxiliary Contact Mount Block is a DPDT (two-pole, double-throw) snap-action limit switch designed for industrial control and machine-safety applications. The 9007-CO3 designation identifies a two-contact-set configuration with two normally open and two normally closed contacts, delivering two independent switching circuits in a single device, typically actuated by a plastic plunger. This model includes an auxiliary contact mount block for adding an additional signaling or interlock contact alongside the main switch. The 9007 CO family is documented as a heavy-duty snap switch used for end-of-travel and interlock sensing in automation equipment.
