Key-operated switch Eaton M22-WRS-A1

The Eaton M22-WRS-A1 key-operated switch is designed for controlled access and reliable operation in control systems. It has a compact plastic housing finished in black and silver and dimensions of 29.7 mm × 39.6 mm × 29.7 mm, making it suitable for installation in confined panels or cabinets. The switch mechanism is operated by a removable key to prevent unauthorized operation and to provide clear on/off or multi-position control depending on panel wiring.

Advantages

The key-operated design ensures that only authorized personnel can change the switch state, reducing accidental or unauthorized operation. The durable plastic housing offers electrical insulation and resistance to typical workshop or industrial environments while keeping the unit lightweight. Its compact footprint simplifies integration into existing control panels and reduces the need for extra mounting space.

Suitable for

• Access control in machinery and production lines
• Secure power or function enable/disable in control cabinets
• Areas where operator authorization is required
• Small enclosures and retrofit panel applications
