This Niles current-sensing 12-volt trigger lets you automatically turn on a secondary device when you power up the first. For example, activate a motorized projection screen when you turn on your front projector. Plug the Niles trigger into an AC outlet, and connect your projector to the trigger's AC input. Then run a mono minijack cable (not included) from the Niles trigger to your screen's 12-volt trigger input. Fire up your projector, and the screen extends — you're ready for movie night.

Note: Due to the CS12V's current limitations, we recommend not using high-current components like most home theater receivers and amplifiers as the triggering device.

Product Highlights:

  • powers up an accessory like a fan or a motorized screen when you turn on your projector or TV
  • choose from three delay settings: 0 seconds, 5 seconds, and 10 seconds
  • compact design
  • integrated mounting wings for horizontal or vertical installation
  • UL-listed
  • 9-1/16"W x 1-5/8"H x 6-1/8"D (with cables connected)
  • warranty: 2 years
  • Our 60-day money-back guarantee

Crutchfield Customer Review (What's this?)

My new projector did not have a screen trigger. The Niles CS12V was exactly what I needed. The Niles product is small enough to hide behind my shelf mounted projector. Installation was simple. Plug the Niles CS12V into the AC outlet, plug the projector and the trigger cable into the CS12V.

A thorough instruction booklet comes with the product. My only critique of the initial set-up instructions is that it fails to explain that you need to press AND HOLD the adjust button.

The CS12V is working perfectly. It is very well constructed. I am very pleased with it's performance.

Product Research


Overview: The CS12V is a current sensing 12-volt (DC) trigger. Plug one of your system components into the 3-prong AC outlet and the CS12V senses the current draw when that component is turned on, and energizes the 12-volt output to turn on a second component.

Note: According to Niles Audio, the power consumption on the component plugged into this unit must be at least 30 watts to trigger the 12 volt output.

Delay: You can delay the 12-volt output when the connected component is turned on. The delay time options are zero seconds, five seconds, and 10 seconds.

Idle Current: Most components draw some nominal current when they're off. With the connected component turned off, set the CS12V to account for that current.


  • Input: 120 volts AC, 60 Hz
  • AC Output: 120 volts, 60 Hz; 5 amps max, 600 watts max
  • Trigger Output: 12 volts DC, 200 mA
  • Output Plug: 3.5mm mono, tip positive
