SMT Gas Pressure switch, suggestion anyone?

[munromh]

I'm trying to find a simple "one bit" inexpensive surface mount pressure switch that will activate at 2 psig and handle excursions to 200 psig. Can't seem to find one.

Also thought about a piezoresistive pressure sensor but the cost is higher than I'd like to pay, a buck or two, for a simple go/no-go function.

Any suggestions?

Thanks,
Mark
