Complete 3-position actuator W3 yellow backlit nickel-plated ring ST22-P3L.G. ST22-P3L.G\.

Three-position push-button actuator with backlight – reliability and functionality in one

This complete push-button actuator, designed for mounting in 22 mm diameter holes, offers three switching positions, making it an ideal solution for controlling various devices and circuits. Made of high-quality materials, it ensures long-lasting and trouble-free operation even in demanding industrial conditions. The yellow color of the control element and the nickel-plated illuminated ring increase readability and facilitate identification, which is particularly important in dynamic work environments.

The actuator is designed for ease of installation and use. The solid construction and high degree of protection IP65 guarantee resistance to dust and moisture ingress, allowing it to be used both indoors and outdoors. A wide operating temperature range (-40°C to +70°C) ensures reliable operation in extreme conditions.

Construction features and user parameters

The actuator's construction is based on a non-latching mechanism, which means that the button position is maintained until pressed again. This solution is particularly useful in applications requiring precise control and preventing accidental changes in circuit state. Additionally, the possibility of backlighting (BA9S lamp socket) improves visibility in low light conditions.

• Three switching positions: Allow you to control three different circuits or functions with a single button.
• Backlight: Increases readability and facilitates identification in difficult lighting conditions. Available lamp voltages: 24/230 V AC and 24/220 V DC.
• High resistance to external factors: IP65 protection class provides protection against dust and splashing water.
• Wide operating temperature range: From -40°C to +70°C guarantees reliable operation in various environmental conditions.
• Solid construction: Ensures long-lasting and trouble-free operation even with intensive use.
• Connection wire cross-section: 2× 1...2.5 mm² (solid) or 2× 0.75...1.5 mm² (stranded) – allows easy connection to the electrical installation.

Applications and compliance with standards

The ST22-P3L.G actuator finds application in a wide range of industrial applications, such as:

• Machine and device control
• Operator panels
• Building automation
• Alarm systems
• Applications requiring precise control of three different circuits

The product meets the requirements of PN-EN 60947-5-1 and IEC 60947-5-1 and IEC 60947-1 standards, which guarantees its safety and reliability. The continuous rated current is 10A and the rated switching current in AC-15 category is 2.5A (at 230V) and 1.6A (at 400/500V). The mechanical durability of the actuator is as much as 300 thousand switching cycles and the switching durability is at least 200 thousand cycles with rated electrical parameters.
