Illuminated rotary push button, 1NO, stable, 0-I, green T0-B100SL20Y

Rotary button – a reliable control element

This rotary button, catalog number T0-B100SL20Y, is a solid and functional solution for controlling electrical circuits. Equipped with a single normally open (1NO) contact and a stable 0-I characteristic, it ensures safe and efficient operation in various applications. Its green color makes it easy to identify, and the ability to illuminate increases visibility in low-light conditions.

Designed for both professional use and end customers, this button finds application in control cabinets, operator panels, and anywhere reliable switching of circuits is required. The construction with IP50 protection degree guarantees resistance to dust and moisture, which translates into a long service life and trouble-free operation even in difficult conditions.

Construction and application

The rotary button from the B series by EMAS ELEKTROTEKNIK is characterized by a simple construction and easy installation. Two positions (0-I) allow for intuitive operation, and a stable characteristic ensures reliable circuit switching. The 1NO contact means that the circuit is open in the "0" position and closed in the "I" position. Illumination increases user comfort, especially in dark rooms or during night work.

Thanks to its compact size, this button can be easily integrated with existing electrical installations. It is ideal for applications requiring frequent circuit switching, such as controlling motors, lighting or heating devices. The ability to illuminate is particularly useful in industrial applications where quick identification of the device status is a priority.
