Rotary Switch – Reliable Control Interface

This rotary switch from the Harmony 9001K series is a robust and functional solution for controlling devices and machinery. It features a durable construction, resistance to harsh operating conditions, and easy installation, making it ideal for both professional installers and end users seeking a reliable control element.

Design and Application

The switch is designed for mounting in holes with a diameter of 31 mm. It features a black, extended handle for comfortable operation, while its construction with a metal front ring ensures durability and resistance to mechanical damage. The switch is two-position, allowing selection between two distinct settings.
