Product Features

  • Electronic switching for all your needs—and it’s safe for your LaserJet® printer!
  • Works locally and remotely with a wide range of input voltages.
  • Choose your remote access port: RS-232, RS-422, RS-485, RS-530, TTL, or dry contacts.


  • Switch remotely through EIA or TTL control signals, or switch locally by turning the knob.
  • Ideal for use in process control and automated environments.
  • Enables both crossover and standard straight-through operation.
  • Great for retail or industrial applications, when you need data on demand.

  • The Local/Remote Electronic Switch works locally and remotely with a number of interfaces and a wide range of input voltages. Because you can switch it remotely through EIA or TTL control signals, it’s smarter than a manual switch. You can switch locally too, just by turning the knob.

    Electronic switching action provides surgeless, spikeless changeovers—something mechanical switches just can’t do.

    NOTE: Also available in ABCDE (4 to 1) and X (2 to 2) versions.
