Rotary switch – reliability and functionality in every circuit

This 2-position rotary switch, designated ST22-P.Z-21, is a solid solution for controlling electrical circuits. Made of high-quality materials, it ensures long-lasting and trouble-free operation in various applications. Its green color and nickel-plated front ring add to its aesthetic appearance, and its compact dimensions make it easy to install even in tight spaces.

Design and parameters for professionals

The switch has a 22 mm hole diameter and is designed for mounting in panels with the same diameter hole. Equipped with a screw connection, it guarantees a secure and safe connection of wires. Its supply voltage range from 24 to 230 V makes it universal and can be used in installations with different voltages. The IP65 protection class provides resistance to dust and moisture, making it an ideal choice for industrial environments and those exposed to harsh weather conditions.

The non-latching design means that the switch remains in the selected position until manually changed – this is particularly useful in applications requiring a stable circuit state. It has one normally open (NO) contact and two normally closed (NC) contacts, allowing for the implementation of various control functions. The front ring material – plastic – ensures durability and resistance to mechanical damage.

Application and benefits

This rotary switch finds application in a wide range of devices and installations:

• Control panels: Ideal for building control panels for machines and industrial equipment.
• Building automation: Excellent for controlling lighting, ventilation or other systems in buildings.
• Electrical devices: Can be used inside various electrical devices as a control element.
• Industry: Resistance to harsh conditions makes it suitable for industrial applications.

Thanks to its solid construction and high-quality workmanship, this switch guarantees reliable operation for a long time, minimizing the risk of failure and downtime. Its versatility allows it to be used in many different applications, making it a practical choice for both installers and end users.
