To ill an A/C system correctly, you need a manifold gauge set so you can see the pressures in the system, to me it sounds like you added too much, and the relief valve opened and vented the R-134a to the atomsphere. Take it to a qualified A/C shop before you succeed in destroying the compressor, or other EXPENSIVE parts!

What is the highpressure cut off switch and what does it do.

It kills the power to the compressor so high pressure does not make it explode!

If a hose? Is clogged? It should be replaced, they can develop an internal tear, this will act as a flap that will close the flow of refridgerant in one direction. If you want it to work, change the bad hose, replace the reciever drier, and orifice tube, evacute and recharge it.
