Multi-Point to Point Switching


MirW Remote Switches allow multiple locations to control relays at a single location. Think of switches throughout a building controlling a generator or a centralized ventilation system. If desired each transmitter board can trigger a different action on the Receiver Board.

  • 2 Mile Range
  • Multiple Transmitters to a Single Receiver
  • Contact Closure on Transmitter Boards
  • Relays on Receiver Board
  • Up to 8 Transmitter Boards per System
  • No Computer, No Programming
  • Relay Flash, Toggle, On/Off, and Timer Control

MirW Remote Switches

MirW Series Switches allow switches in multiple remote locations to control relays installed in a single location. MirW series controllers accept contact closure inputs, and may be used to trigger many types of relays, from high-power solid state relays to low-power mechanical relays. MirW series controllers are sold in groups, including a specialized MirW relay controller and multiple remote transmitters. MirW packages are created on using our web site, and come pre-configured to work out of the box. A contact closure from any of the remotes will directly control a corresponding MirW relay.

MirW Remote Switches

With NCD you know you have a proven reliable, easy to use, and extensible product because we’ve been in the business for over 20 years. This means you don’t have to spend valuable time researching how to jig-saw pieces of your project together to get them to work cohesively. Being manufactured in the U.S.A. you know you’ll get good support and a quality product. NCD also ensures you won’t have to put any time into soldering or building a PCB, just pick your boards and power them up. Knowing that every sensor, relay controller, and component is built around the same concept will save you guess work on how well software will work with any board.

How It Works

MirW controllers include multiple transmitters and a single relay controller. NCD technical support pre-configures the transmitters to work with the MirW shipped in your order. MirW transmitters should be thought of as a programmable remote control with contact closure inputs. When contact closure inputs are closed, the MirW transmitter sends a pre-configured command to the relay controller to activate relays for your specific application. MirW transmitters can be configured by the user to trigger timers, toggle relays, turn relay groups on and off, or flash individual relays.

Wireless Remote Switching

Wireless Remote Switching may be the easiest option as it only requires 12 volts of power at the install locations and be within wireless range of each other. When it comes to the wireless range you should remember that the range we list is a line of sight range. A 1 mile range line of site can be cut down to a few hundred feet with a thick wall between them.
