Johnson P70LB-1C Dual Pressure Control 20"-100# Both Auto Reset

This P70 Series of dual pressure controls employs a SPST switch, that is opened when either high pressure or low pressure beyond the control settings is sensed at the control’s two bellows sensing elements. The load carrying contacts provide direct control of AC motors within the control’s rating. These controls provide close high–open low (low pressure) or open high– lose low (high pressure) contact action.
