What is this (Heater/AC)?

What is the electrical device in this picture and what does it do?
Is it needed for the heater?

I'm currently trying to re-install the heater in my truck.
*it originally came with A/C, but that was removed by a previous owner.

It is the AC compressor switch that engages the compressor when AC is needed.
