PSW 852 BK General Purpose Industrial Pressure Switch with 2 Outputs 13730

 The PSW-850 is a simple, economical control for processes which require multiple switching capabilities. Dual or triple-switch controls provide multi-outputs in applications such as alarm and shutdown, pre-alarm and alarm, high/low limit or level staging functions.

Triple-switch models have been used for liquid level control. In this application, three pressure settings correspond to 'pumping out' elevations in a sump pump.
