The Aqua Lung Switch Block can be used with any diving full face mask or helmet with a Medium Pressure (i.e. less than 16 bar / 232 psi) air supply. The switch block allows the diver to switch from the primary air supply to an alternate bailout air supply (or Emergency Gas Supply – EGS), in case of failure of the primary supply. The primary supply may be a surface-supply umbilical or SCUBA cylinder. The switch block is attached to the divers’s harness in an easily accessible location so the diver can open the Switch Block valve unaided and in nil visibility conditions.
