Description
The Johnson Controls P70EE-1 is a mechanical snap switch designed for rugged outdoor applications on HVAC systems. This is one weatherproof unit that has an exterior enclosure (ENC) to protect against detrimental conditions of the physical environment. This switch behaves as an SPDT switch that can control two different electric circuits in relation to the pressure fluctuation. A pressure-sensitive diaphragm adjusts to events inside the system with pressure range of 1250/7, which is 175 to 425 psi. When the pressure gets to the user adjusted set point, the P70EE-1 triggers the “Open-Low” switch action.
