Double-button switch 2 C/O white-black AC ST22-2KL-20-230-LED\B/CZ

Double-button switch for a wide range of applications

This double-button control switch, designated ST22-2KL-20-230-LED\B/CZ, is a reliable solution for controlling electrical circuits. Designed for both professional use by installers and end customers, it combines a solid construction with functionality. This button is used in machine control panels, switchboards and other devices requiring precise and safe control.

Construction and user parameters

The button is characterized by a round lens shape and a solid front ring made of plastic. Its construction provides a high degree of protection IP65, which guarantees resistance to dust and moisture – important in harsh industrial conditions. The mounting hole diameter is 22 mm, making it compatible with most standard control panels. The button color is a combination of red and green, which facilitates visual identification of functions.

Thanks to two control positions, the button allows operation of two independent circuits or functions. It is designed to operate at 230V AC, and its continuous rated current is 10A. Short-circuit protection of the switch contacts is provided by a 10A fuse or 1kA fuse. The mechanical durability of the button is as much as 3 million switching cycles, which proves its long service life.

Additionally, the button has the possibility of connecting a signal lamp (BA9S base) with a power of 1W (LED) or 2W (bulb), which increases its functionality and allows visual control of the circuit status. Connection cables should have a cross-section of 1...2.5 mm² (solid) or 0.75...1.5 mm² (stranded).

Application and compliance with standards

The ST22-2KL-20-230-LED\B/CZ button meets the requirements of PN-EN 60947-5-1 and IEC 60947-5-1 and IEC 60947-1 standards, which confirms its safety and reliability. It can be used in a wide range of industrial and automation applications, such as:

• Electric motor control
• Machine and equipment operation
• Production process automation
• Alarm and signaling systems
• Operator panels

Resistance to vibrations (up to ± 1 mm amplitude) and shocks (up to 15g) make it an ideal choice for environments with increased mechanical requirements. Operation at temperatures from -40°C to +70°C ensures reliability even in extreme environmental conditions.
