2-position rotary switch red 2 NO illuminated 24 nickel-plated ring ST22-PL.C-20-24-BA9S. ST22-PL.C-20-24-BA9S\.

Signal indicator – reliable indication of device status

This 2-position rotary switch, in a red housing, is a solid solution for signaling the operating status of devices and installations. Backlighting with a nickel-plated ring ensures clear visibility even in low light conditions. Designed for mounting in 22 mm diameter holes, it can be used in control panels, as well as in industrial machines and equipment.

Construction and operating parameters

The switch is characterized by a universal supply voltage range from 24 to 230V, which allows it to be used in various systems. Screw connection ensures a secure and durable electrical connection. The IP65 protection class guarantees resistance to dust and water ingress, enabling operation in harsh industrial conditions. The front ring made of high-quality plastic provides mechanical strength and resistance to external factors.

Functionality and application

Thanks to two switching positions and two normally closed contacts, the switch can be used to control various electrical circuits. Non-self-return means that the switch position is maintained until manually changed. The built-in light source (BA9s) and red lens provide clear visual indication of the device status. This is particularly useful in applications requiring quick identification of problems or machine operating status. Ideal for operator panels, production machines or building automation systems.
