Square D 9001-KA-1 Selector Switch with Contact Block

Square D 9001-KA-1 Selector Switch with Contact Block combines a selector switch with a KA1 contact block to provide a single Form C/O contact (one normally open and one normally closed) in a compact package. The KA1 block is rated for up to 10 A at 600 V AC and features Fingersafe terminals for safer wiring in industrial panels. This two-path arrangement lets one actuator control two circuits or supply complementary signaling—ideal for interlock logic, machine-state signaling to PLC inputs, or coordinating a starter or other loads in automation panels. As part of Schneider Electric’s Harmony family, the 9001-KA-1 offers a robust, plug‑and‑play interface for control panels that require a two-signal switching solution without external hardware. Common applications include signaling a machine state to a PLC and interlocking safety circuits in automation enclosures.
