Phoenix Contact RS20 Series Rotary Switches are made from high-quality materials, in a compact design and have a long mechanical and electrical service life. They are internationally approved and can be used up to 20 A and 690 V. Thanks to their compact design and the conductor connection direction, the rotary switches are ideal for switchgear in which space is limited. All terminal screws are enclosed in the housing thereby preventing contact with live parts in accordance with BGV A2. Non-conductive parts are made of plastic, which means, for example, that voltage cannot be transmitted to the control cabinet panel.
