Double-button switch 2 C/O green-red AC/DC ST22-2KL-20-24-LED\Z/C

Two-button control unit – reliability and functionality in one

This two-button control unit, designated ST22-2KL-20-24-LED\Z/C, is a solid solution for controlling electrical circuits. Designed for mounting in 22 mm diameter holes, it is perfect for machine control panels, electrical cabinets and other industrial applications. Its construction provides high resistance to mechanical damage and external factors, guaranteeing long-lasting and trouble-free operation.

Construction and user parameters

The button is characterized by a clear red-green marking of the keys, which facilitates the identification of functions. Made of high-quality plastic front ring provides an aesthetic appearance and additional protection against moisture and dust (IP65 protection class). This allows the button to be used even in harsh environmental conditions. The construction with two switching tracks allows for flexible use in various control systems.

Solid construction and durability

The button was designed with intensive use in mind. Mechanical endurance at the level of 3 million switching cycles and 0.2 million switching cycles at rated parameters confirm its reliability. Vibration and shock resistance (compliant with IEC 60068-2-6 and IEC 60068-2-27 standards) make it an ideal choice for industrial applications exposed to dynamic loads. A wide operating temperature range (-40°C to +70°C) allows it to be used in various climates.

Mounting and compatibility

The button is designed for mounting in standardized holes with a diameter of 22 mm. The possibility of connecting wires with a cross-section from 1 to 2.5 mm² (solid) or from 0.75 to 1.5 mm² (stranded) ensures easy integration with the existing electrical installation. Compliance with PN-EN 60947-5-1 and IEC 60947-5-1 standards guarantees safety of use and compatibility with other elements of the control system.
