Protruding red button 2 NC 2 NO nickel-plated ring SP22-WC-14. SP22-WC-14\.

Red control button with nickel-plated ring

This protruding button, in a red housing, is designed for applications requiring reliable control of electrical circuits. Manufactured by the renowned SPAMEL, model SP22-WC-14 is characterized by a solid construction and a high degree of protection IP65, making it an ideal solution for both industrial applications and demanding environmental conditions. The button has a self-returning mechanism, meaning it returns to its initial position when released.

Construction and application

The SP22-WC-14 button has been designed for easy installation and intuitive operation. The mounting hole diameter is 22 mm, ensuring compatibility with most standard control panels. Equipped with a screw connection, it allows for quick and secure connection of wires. The red color of the button provides good visibility and facilitates identification of the function in the control system. The front ring made of gray plastic adds aesthetics and protects against mechanical damage.

This button finds application in a wide range of devices and machines, such as:

• Control panels
• Electrical switchboards
• Industrial equipment
• Building automation
• Alarm systems

Electrical characteristics and safety

The SP22-WC-14 button offers a configuration of 4 normally open (NO) and 1 normally closed (NC) contacts, allowing for the implementation of various control functions. Compliance with PN-EN 60947-5-1 and IEC 60947-5-1 standards guarantees safe use and compliance with electromagnetic compatibility requirements. The rated insulation voltage Ui is 500 V, and the rated operating current Ie in category AC-15 is 2.5 A (at 230 V), while in category DC-13 – 4 A (at 24 V). Thanks to this, the button can be used in circuits with different voltage and current. The ambient operating temperature is in the range of -40°C to +70°C, and storage also from -40°C to +70°C. The cross-section of connection wires is 2× 1...2.5 mm² (solid) or 2× 0.75...1.5 mm² (stranded).
