Binary switch? What is its purpose?

I installed an air conditioning system in a 55 Chevy and didnt install the binary switch.
1-What is the purpose of the Binary switch?
2-Would it damage the compressor by not installing the Binary switch.

Thanks
Doug

The purpose of the binary switch is to turn the compressor clutch off when the refrigerant pressure gets too high, to prevent damage to components and catastrophic failure. The binary switch will also keep the compressor from coming on when then the pressure is too low, like when the outside temp is too cold, or if the system has lost it's charge.

Binary Switch

Thanks for the info.
When I turn on the AC the Compressor squeeks.
1-Does that mean I Damaged it by not installing the Binary switch?
2- If so, can the compressor be rebuilt?

Regards
Doug

I have never heard of it being called a binary switch. Unless you had some high pressure(over 300) . I would consider the low pressure switch more inportant( this shuts the compressor off when it reaches below 20. Freon leaks are more prone than high pressure in the system, but it should still be installed.

With R134 systems the high pressure can get really high (more so than R12)damaging compressor components and blowing hoses, that is why it's important to have a high pressure cut off employed.

Yep---what Vince said.

Also---there is a trinary switch. Does the same as the Binary switch with the added feature of sending a signal to the engine cooling fans when the AC is turned on. (handy if you have electric cooling fans, or an auxiliary cooling fan)

That depends on how high the pressure got, and how long it was run that high. If your system is still operating properly I would suspect you are OK.
