[DML] Low Pressure Cut Off Switch for r134a?

[Stephen Rice <stevedmc@xxxxxxxxx>]

Does anyone know if there is a better low pressure switch to use for
r134a applications?  I am currently using my stock switch with r134a
and am very happy since my vent temp is 43 degrees.

The reason I am asking is a friend of mine suspects his low pressure
switch to be bad and if there is a better switch to use for r134a he
would like to go that route.

I did a little research and it looks like the stock switch cross
references with a 1980 Buick Centruty.  The part number at AutoZone is
MT0207 and its $10.99.  Has anyone found a better part to use for
r134a?

Another question would be, can he remove the switch without evacuating
the system or will this open the system when he unscrews it?

Thanks,
