Ohmite 3129T2 High-Current Rotary Switch

Ohmite power tap switches (high power rotary switches) are constructed to provide dependable, convenient operation. These switches offer high current handling capability in a small package, featuring ceramic or polyester construction and silver alloy contacts. They are suitable for various industrial applications where reliable switching of AC or DC power is required. Tandem assemblies are available as standard models, and the switches are UL listed for specific models. The non-shorting design disconnects the previous circuit before establishing contact for the succeeding tap, enhancing safety and preventing potential issues.
