Spamel SP22-B-01 Control Pushbutton 22mm Red Non-Self-Resetting 1NC

The Spamel SP22-B-01 is a professional-grade 22mm industrial control pushbutton designed for demanding electrical environments. Featuring a distinct red actuator, this switch utilizes a non-self-resetting, or maintained, mechanism, ensuring that the contact state remains active until manually toggled. It is engineered with one normally closed (1NC) contact block, providing reliable performance for critical control circuits in automation systems and industrial machinery.

Advantages

This control pushbutton offers exceptional durability and consistent performance in industrial settings. The maintained action design is ideal for applications where a persistent signal or state is required without the need for continuous operator pressure. Its standard 22mm mounting diameter ensures broad compatibility with existing control panels and enclosures, while the robust construction guarantees long-term operational reliability even in frequent-use scenarios.

Suitable for

• Industrial control panels and automation systems
• Emergency stop or safety-related circuit interruption
• Machinery control interfaces
• Electrical distribution boards
• Maintained state switching applications

When it may not be suitable

This device is not intended for applications requiring momentary or spring-return switching, where the contact must automatically revert to its original state upon release. It is also not suitable for high-power direct load switching without appropriate contactors or relays.

Key specifications

• Mounting diameter: 22mm
• Actuator color: Red
• Switching mechanism: Non-self-resetting (maintained)
• Contact configuration: 1NC (Normally Closed)
• Application: Industrial control and automation

How to use

The pushbutton is designed for panel mounting through a standard 22mm hole. Secure the device using the provided locking nut to ensure a firm fit against the panel surface. Connect the electrical wires to the 1NC contact terminals according to your circuit diagram. Once installed, pressing the red actuator will open the circuit, and it will remain in that state until manually reset or toggled back to the closed position.

What to consider before purchase

• Verify that your control circuit requires a normally closed (1NC) contact configuration.
• Ensure the 22mm mounting hole size is compatible with your existing panel layout.
• Confirm that a maintained (non-self-resetting) action is appropriate for your specific safety or operational requirements.

Usage recommendations

Regularly inspect the terminal connections for tightness and ensure the actuator moves freely without obstruction to maintain optimal safety and performance in your electrical system.
