What's the difference between a binary and a trinary switch? 

You just made it easy for anyone who wants to do this themselves Thank you for taking the time to make this video

Thank you for such a simple and straight forward explanation.

Super clear. Thank you.

Excellent presentation, clear and simple to understand.

Thank you for easy to understand explanation. I really appreciate it

Well Done! This will be very helpful. Thank You!

Nice job sir

Excellent detailed video THAKS!

Great video thank you. I have been trying to figure out why I have both a binary and trinary switch on my receiver dryer. It's an aftermarket install.... Seems like it is redundant safety that won't hurt...

good video sir

Nice job boss

Thanx

Thank you sir

Thanks for the great video and information. Quick question if you have a second: We have a VA system using a stock mechanical fan, but we're getting some overheating. So, we are adding an additional pusher electric fan to help out. This fan will be mounted in front of the condenser. We had originally been planning to just stay with the binary switch and splicing into the compressor activation wire into the fan controller. However, we read about how VA recommends trinary switches for electric fans, so we were now making plans to change out the binary to a trinary switch. But, after doing more reading, and watching your video, I'm wondering if that is completely necessary. The VA system has worked well with the mechanical fan, even when the engine runs hot. If the main benefit of the trinary switch is to get the fan turned on early, knowing that with a binary switch our fan will turn on immediately, is there another reason to go with the trinary switch over a binary when using both a mechanical and auxiliary electric fan? Thank you for any advice and for the great video.

binary switches are only on the hight side lines? also do you have a link for the safety switch adaptor fitting (threaded)

Hi you said on trinary switch for e fan turns on at 254 pounds,but a what pressure turns off ,thanks in advance

Would this system still activate the A/C fan when the car is at cruise speeds? Or would the air flow through the condenser drop the high side pressure enough to turn the fan off?

Need help with wiring vintage air with the efi sniper unit and trinary switch I have dual fans already wired one to the unit direct and one to a solid state relay can u help

I am trying to install an aftermarket 12V ac unit. It came with a binary pressure switch and a 80C/176F temperature sensor/switch, you mention engine temperature any idea where I should mount this? Maybe just somewhere on the side of the condenser? Should I just swap it out for a trinary and not even bother? Much appreciated if you can find the time to respond.

Great video.. thank you~🏆 I can barely reach the low pressure switch.. silly question.. how do I remove it? (please don't say "carefully" .. ha) Is there a special tool~?

Where can I get a trinary switch from?

Okay cool so I’ll use the binary switch with my mechanical fan.
