Changeover switch
  • Changeover switching
    Provides reliable operation of your device. A smooth and safe transition from one power source to another is paramount.
  • One terminal per pole
    Having one terminal per pole for the entire product range eliminates the need for additional mounting kits.
  • Compactness
    Switches are 20% smaller than other similar products on the market. Saving space and materials.
