Description
The Manifold Pressure Switch is designed to be fitted directly to the manifold to give an electrical indication of any pressure present in the manifold. The pressure switch is available in two configurations, non-latching and latching.
Non-latching Pressure Switch - When sufficient pressure is available, the pressure switch will automatically close the contacts on the micro-switch. When the pressure in the manifold drops sufficiently, the pressure switch will automatically reset, thus opening the contacts of the micro-switch. In this configuration, the switch is commonly used to indicate presence of pressure in the manifold.
Latching Pressure Switch - When sufficient pressure is available, the pressure switch will automatically close the contacts on the micro-switch. At this point a detent device locks the pressure switch in the “pressurised” position. Once the pressure in the manifold has dropped sufficiently, the pressure switch can be reset by gently pulling out the detent knob. In this configuration, the switch is commonly used to indicate whether the CO2 system has been “fired”, as the switch remains closed after the manifold pressure drops.
