Protruding button red 3-way nickel-plated ring ST22-WC-03. ST22-WC-03\.

Control button – reliability and durability in every circuit

This red button, protruding with a nickel-plated ring, with a 22 mm diameter hole, is a solid element of every control panel. Designed for both professional installers and end-users, it provides safe and convenient device control. Made of high-quality materials, it guarantees long-lasting and trouble-free operation in demanding industrial conditions.

Construction and parameters

The button is characterized by a high degree of protection IP65, which means resistance to dust and water – an ideal solution for applications in harsh environmental conditions. The front ring made of durable plastic provides additional protection and an aesthetic appearance. Screw connection facilitates quick and secure wiring. The button has three normally open contacts, allowing its use in various control applications. Non-latching means that after pressing the button, it remains pressed until released again – this is important in applications requiring signal maintenance.

Application and compliance with standards

The SP22-WC-03 button finds application in a wide range of electrical devices and installations, such as:

• Control panels for machines and industrial equipment
• Building automation
• Alarm systems
• Lighting control
• Applications requiring reliable starting and stopping of devices

It meets the requirements of PN-EN 60947-5-1 and IEC 60947-5-1 standards, which confirms its safety and compliance with applicable standards. The rated insulation voltage Ui is 500V, and the rated operating current Ie in category AC-15 is 2.5A (at 230V), while in category DC-13 it is 4A (at 24V). The cross-section of the connecting wires is 2x1...2.5 mm² (solid) or 2x0.75...1.5 mm² (stranded). The ambient operating temperature is in the range of -40 to +70°C.
