Spamel ST22-P.CZ-10CZ 2-Position Selector Switch, 22mm, Black, 1NO, Non-Illuminated, Maintained

The Spamel ST22-P.CZ-10CZ is a professional-grade 2-position selector switch engineered for reliable manual control in industrial and automation environments. Designed for standard 22mm mounting holes, this robust rotary switch features a sleek black finish and a maintained action mechanism, meaning it stays in the selected position until manually moved. It is equipped with a 1NO (normally open) contact block, ensuring dependable electrical connectivity for your control circuits.

Advantages

This selector switch stands out due to its durable construction and ease of integration into existing control panels. The maintained action provides clear operational status, as the switch remains in its set position without the need for constant pressure. Its standard 22mm diameter ensures compatibility with a wide range of enclosures and panels, while the high-quality materials used in its manufacturing guarantee long-term performance even in demanding industrial settings.

Suitable for

• Industrial control panels
• Automation and robotics systems
• Machinery start/stop operations
• Electrical distribution boards
• Process control equipment

When it may not be suitable

This switch is not intended for applications requiring momentary switching, where the actuator must return to its original position automatically upon release. It is also not suitable for environments that require illuminated indicators, as this specific model is non-illuminated.

Key specifications

• Mounting diameter: 22mm
• Switch positions: 2
• Contact configuration: 1NO (Normally Open)
• Action type: Maintained (non-spring return)
• Color: Black
• Illumination: None

How to use

To install the switch, insert the actuator through a 22mm hole in the control panel and secure it using the provided locking nut. Connect the electrical wires to the 1NO contact block terminals according to your circuit diagram. Once installed, simply rotate the selector knob to toggle the contact state between the two positions. The switch will remain in the chosen position until it is manually rotated back.

What to consider before purchase

• Verify that your panel has a 22mm mounting hole available.
• Ensure that a 1NO contact configuration meets your specific circuit requirements.
• Confirm that a maintained action (non-spring return) is appropriate for your intended application.
• Check the space behind the panel to ensure sufficient clearance for the contact block.

Usage recommendations

Regularly inspect the switch for any signs of mechanical wear or loose wiring connections to ensure continued safe and reliable operation in your electrical system.
