Spamel ST22-DC-01 Mushroom Push Button Red 22mm 1NC

The Spamel ST22-DC-01 is a high-quality mushroom-style push button designed for integration into industrial control systems and electrical panels. Featuring a prominent red actuator, this device is specifically engineered for 22mm mounting holes, making it a standard choice for control consoles and machinery interfaces. With a 1NC (normally closed) contact configuration, it ensures reliable circuit interruption when pressed, providing a robust solution for manual control and safety-critical operations.

Advantages

This push button offers exceptional durability and consistent performance in demanding industrial environments. Its ergonomic mushroom head design allows for easy and rapid activation, which is essential for emergency stop scenarios or quick manual overrides. The construction materials are selected to withstand frequent use, ensuring a long service life and minimal maintenance requirements. Furthermore, the standardized 22mm diameter simplifies installation and replacement processes across various types of automation equipment.

Suitable for

• Emergency stop systems in industrial machinery
• Manual control panels for automation lines
• Electrical distribution boards
• Safety circuits requiring a normally closed contact
• Control interfaces for heavy-duty equipment

When it may not be suitable

This device is not intended for applications requiring a normally open (NO) contact configuration without additional wiring or adapters. It is also not suitable for outdoor environments exposed to direct weather conditions unless housed within an appropriately rated protective enclosure.

Key specifications

• Actuator type: Mushroom head
• Color: Red
• Mounting diameter: 22mm
• Contact configuration: 1NC (Normally Closed)
• Application: Industrial control and safety systems

How to use

To install the Spamel ST22-DC-01, insert the actuator through a pre-drilled 22mm hole in your control panel or enclosure. Secure the device using the provided locking nut to ensure it is firmly fixed in place. Connect the electrical wires to the 1NC contact terminals according to your circuit diagram. Once installed, the button is ready for operation; pressing the mushroom head will open the circuit, and releasing it will return the contact to its closed state.

What to consider before purchase

• Verify that your control panel has a 22mm mounting hole available.
• Ensure that your system logic requires a normally closed (1NC) contact.
• Check the space behind the panel to accommodate the depth of the contact block.
• Confirm the voltage and current ratings of your circuit match the device specifications.

Usage recommendations

Regularly inspect the push button for any signs of physical damage or debris accumulation that might hinder its operation. Ensure that the electrical connections remain tight and free from corrosion to maintain optimal performance in your control system.
