Product Description
Benefits & Applications
The Eaton M22-KC01 is a compact dual contact block featuring 1 Normally Open (1NO) and 1 Normally Closed (1NC) auxiliary contact, designed for use with Eaton’s modular M22 pushbuttons, selector switches, and operator devices. This stacked NO/NC configuration makes the M22-KC01 ideal for control circuits requiring both start and stop signaling, interlock logic, safety functions, and PLC input feedback.
Built for long mechanical endurance and dependable switching performance, the M22-KC01 is a preferred choice for industrial control panels, OEM machinery, building automation, and motor control systems. Its tool-free, snap-on design ensures quick installation while maintaining secure electrical connections, even in high-vibration environments.
Typical Applications
- Start/stop pushbutton stations (NO for start, NC for stop)
- PLC and automation feedback circuits
- Machine interlocks and safety control logic
- Motor control and contactor signaling
- Industrial automation and OEM equipment panels
Technical Advantages
- 1NO + 1NC stacked auxiliary contacts for versatile control logic
- Tool-free snap mounting to M22 operator devices
- High reliability for low-voltage control circuits and PLC inputs
- Long mechanical and electrical endurance
- Compact modular design simplifies panel layout
- Compatible with all Eaton M22 pushbuttons, selectors, and E-stops
Compatibility Notes
The M22-KC01 is part of Eaton’s M22 modular operator system and is compatible with:
- M22 momentary and maintained pushbuttons
- M22 selector switches and key switches
- M22 emergency stop operators

If your application requires a dual auxiliary contact configuration (1NO + 1NC) for interlocks, start/stop circuits, or control feedback, the M22-KC01 is the correct OEM accessory.
Frequently Asked Questions
Q: What does “KC01” mean in the M22-KC01 part number?
“KC01” indicates a stacked auxiliary module with 1 Normally Open (1NO) and 1 Normally Closed (1NC) contact.
Q: Which Eaton operators is the M22-KC01 compatible with?
It works with all Eaton M22 pushbuttons, selector switches, key switches, and E-stop operators.
Q: Can I combine the M22-KC01 with additional contact blocks?
Yes. M22 modules are fully modular and can be stacked to create multi-stage NO/NC combinations for complex control requirements.
Q: Is the M22-KC01 suitable for PLC inputs?
Yes. Both the NO and NC contacts provide clean, low-level switching ideal for PLC digital input circuits.
Q: What is the difference between M22-KC01 and M22-KC10?
The M22-KC01 is 1NO + 1NC, while the M22-KC10 is configured as 1NC + 1NO but in reverse stacking order. Electrical function is the same; the difference is physical stacking orientation.
