Protruding red button in OBC 2 normally open, nickel-plated ring SP22-WC-20/OBC/A

Control button – reliability and functionality in every application

This protruding red button, designated SP22-WC-20/OBC/A, is designed for mounting in 22 mm diameter holes. It finds application in both simple control systems and more complex industrial systems. Its construction ensures comfortable operation and durability, and the IP65 protection rating guarantees resistance to dust and moisture – which is crucial in harsh working conditions.

Construction and characteristic features

The button is characterized by a solid construction using plastic on the front ring and nickel-plated finish, which affects its aesthetics and corrosion resistance. It has two switching contacts (2Z), which provides flexibility in configuring control circuits. Automatic return to the initial position after pressing facilitates operation and increases safety. Thanks to this solution, after releasing the button, the circuit automatically returns to its initial state.

The button meets the requirements of PN-EN 60947-5-1, IEC 60947-5-1 and IEC 60947-1 standards, which confirms its compliance with European safety and quality standards. The cross-section of the connection wires is 2× 1...2.5 mm² (solid) or 2× 0.75...1.5 mm² (stranded), which ensures easy connection to the existing installation. The rated insulation voltage Ui is 500 V, and the rated switching currents are 2.5 A (AC-15) and 4 A (DC-13) at 24 V, 1 A at 110 V and 0.25 A at 220 V. The ambient operating temperature is in the range of -40°C to +70°C.

Applications and benefits

This button is perfect for anywhere that requires reliable signaling or process control. It can be used in:

• Control panels: as an element to start or stop machines and devices.
• Alarm systems: for immediate reporting of failures or threats.
• Industrial applications: in environments exposed to harsh operating conditions (dust, moisture).
• Automation devices: as a user interface element.

Thanks to its versatility and solid construction, this button is an investment in the long-term and trouble-free operation of control and signaling systems. The IP65 protection rating provides peace of mind when used in demanding environmental conditions.
