Spamel ST22-B-01 Emergency Stop Button 22mm, Turn-to-Release

The Spamel ST22-B-01 is a professional-grade emergency stop button engineered for integration into industrial control panels and safety-critical systems. Designed for standard 22mm mounting apertures, this device provides a reliable and immediate method for halting machinery operations during hazardous situations. Its robust construction and intuitive turn-to-release mechanism ensure that the switch remains secure during normal operation while allowing for quick and effective activation when safety is compromised.

Advantages

This emergency stop button stands out due to its high durability and resistance to the rigors of industrial environments. The turn-to-release functionality prevents accidental resets, ensuring that the system remains in a safe state until a deliberate manual action is taken by an operator. Its standardized 22mm design facilitates seamless installation into existing control panels, making it a versatile choice for both new equipment builds and maintenance upgrades in various manufacturing and automation sectors.

Suitable for

• Emergency shutdown systems for industrial machinery
• Control panels in manufacturing and assembly lines
• Safety circuit management in automated production environments
• Electrical control cabinets requiring manual safety overrides

When it may not be suitable

This device is not intended for use in environments with extreme corrosive chemicals or high-pressure washdown requirements unless housed in a compatible protective enclosure. It is also not suitable for applications requiring a key-lock reset or specialized illuminated feedback, as this model relies on a standard mechanical turn-to-release action.

Key specifications

• Mounting diameter: 22mm
• Operation type: Turn-to-release
• Application: Emergency stop safety switch
• Design: Industrial grade for control panels

How to use

To install the Spamel ST22-B-01, insert the actuator through a standard 22mm hole in the control panel and secure it using the provided locking nut. Connect the appropriate safety circuit wiring to the contact blocks according to your machine's electrical schematic. In an emergency, press the button head firmly to engage the stop function. To reset the system, rotate the button head in the direction indicated by the arrows until it clicks back into the operational position.

What to consider before purchase

• Verify that your control panel has a standard 22mm mounting hole
• Ensure the contact block configuration matches your safety circuit requirements
• Confirm the environmental conditions are suitable for standard industrial switchgear

Usage recommendations

Always perform a functional test of the emergency stop circuit after installation and during routine maintenance schedules to ensure the safety system remains fully operational.
