Rotary control button with actuator 3-position (I-0-II), yellow (2NO), nickel-plated ring, ST22-P3.G-20. ST22-P3.G-20\.

Control button – a reliable element of your installation

This three-position control button with a knob and spring (I-0-II) is a solid solution for both professional installers and end users. Designed for mounting in 22 mm diameter holes, it provides convenient and precise control of electrical circuits. Its yellow color and nickel-plated ring add an aesthetic look, and the durable construction guarantees long-lasting reliability.

Construction and application

This button, designated as ST22-P3.G-20, is equipped with two normally open contacts (2NO) and zero normally open contacts. The three-position design (I-0-II) allows you to control devices in three operating modes: on, off, and an additional mode, depending on the specifics of the installation. It will work in applications requiring frequent switching of circuits, such as controlling motors, lighting or machines. Thanks to the standard mounting hole diameter (22 mm), it can be easily integrated with existing control panels.

Key features and benefits

• Durable construction: Made of high-quality materials, resistant to mechanical damage and environmental conditions.
• Versatile application: Ideal for control panels in industry, construction or home automation.
• Convenient operation: The knob with spring provides precise and intuitive switching between operating modes.
• Easy installation: Standard mounting hole size (22 mm) simplifies integration with existing installations.
• Clear markings: The yellow color of the button makes it easier to identify and quickly switch functions.
• Safety: Ensures reliable operation and safe operation of electrical devices.
• Aesthetic appearance: The nickel-plated ring gives the device an elegant look, suitable for modern control panels.

Technical parameters in practice

The ST22-P3.G-20 button has been designed with demanding industrial and commercial applications in mind. Its solid construction and precise workmanship guarantee reliable operation for a long time. Thanks to two normally open contacts, you can connect two independent circuits that will be active in the "I" position. The lack of normally open contacts means that the button is mainly used to switch on circuits, not to switch them off. The IP65 protection class provides resistance to dust and a water jet under low pressure – which is particularly important in harsh industrial conditions.
