3-position rotary switch white 2 NO illuminated 230 V nickel ring ST22-P3L.B-20-BA9S\230

Universal 3-position switch – reliability and functionality

This 3-position rotary switch, with backlighting and nickel-plated ring, is a solid solution for controlling electrical circuits. It is suitable for both industrial installations and home applications where reliability and ease of use are required. The design with three positions allows for precise control of devices, and the backlighting ensures good visibility in low-light conditions.

Construction and application

The switch is designed for mounting in 22 mm diameter holes. Made of high-quality materials, it ensures long-lasting and trouble-free operation. Screw connection guarantees secure and stable wire connections. A wide range of supply voltage (24…230 V) makes it a universal solution, adapted to various needs. The IP65 protection class means resistance to dust and water jet, which allows its use in harsh environmental conditions.

Key features and benefits

• Three switching positions: Allow precise control of electrical devices.
• Backlighting: Increases comfort of use, especially in dark rooms or at night. Uses a BA9S lamp holder with a power of 1W (LED) or 2W (bulb).
• High resistance to external conditions: IP65 protection class guarantees protection against dust and moisture – ideal for workshops, production halls or outdoor facilities.
• Universal supply voltage: The ability to operate in the range of 24…230 V increases installation flexibility.
• Solid construction: High-quality materials ensure durability and reliability of the device. The front ring made of plastic provides an aesthetic appearance and additional protection.
• Safety: Short-circuit protection of the switch circuits at 10 A (fast fuse insert) and compliance with PN-EN 60947-5-1 and IEC 60947-5-1 standards ensure safe operation.
• Easy installation: Screw connection facilitates wire connection, and the standard mounting hole (22 mm) ensures compatibility with most control cabinets.

Operating parameters

The device is characterized by high mechanical durability (0.3 million switching cycles) and connection durability (0.2 million cycles at rated voltages and currents). Designed to operate in a wide range of ambient temperatures (-40…+70°C) and resistant to vibrations and shocks, as confirmed by tests in accordance with IEC 60068-2-6 and IEC 60068-2-27 standards. The cross-section of the connection wires is 2 x 1...2.5 mm² (solid) or 2 x 0.75...1.5 mm² (stranded).
