• Machinery start-stop and mode selection
• Secure access control for electrical equipment
• Power distribution systems
• Heavy-duty manufacturing environments

When it may not be suitable

This switch is not intended for use in environments requiring high-speed momentary switching, as it is a maintained key-operated device. It is also not suitable for applications where a higher number of contact blocks or specific NC (normally closed) configurations are required beyond the provided 1NO specification.

Key specifications

• Mounting diameter: 22mm
• Switch positions: 3
• Contact configuration: 1NO (Normally Open)
• Operation type: Key-operated
• Color: Black

How to use

To install the switch, insert the unit into a pre-drilled 22mm hole on your control panel and secure it using the provided locking nut. Connect the electrical wires to the 1NO contact terminals according to your circuit diagram. Once installed, insert the key and rotate it to the desired position to engage or disengage the circuit. Always ensure the power is disconnected before performing any wiring tasks.

What to consider before purchase

• Verify that the 22mm mounting hole size matches your panel requirements.
• Ensure the 1NO contact configuration meets the needs of your specific control circuit.
• Confirm that the 3-position functionality aligns with your operational requirements.
• Check the environmental conditions to ensure the switch is suitable for the intended location.

Usage recommendations

Regularly inspect the key mechanism and contact terminals for signs of wear or debris to maintain optimal performance. Ensure that the key is stored in a secure location accessible only to authorized operators.
