Switch Block (For Use With AGA & OTS Full Face Masks)

The Switch Block has been designed to be used with the Interspiro Divator AGA and OTS full face mask with a Medium Pressure (i.e. less than 16 bar / 232 psi) air supply. The switch block receives air hoses from the main and bailout cylinders and allows the diver to switch from the primary air supply to an alternate bailout air supply in case of low or failure of the primary supply. The switch block is attached to the diver’s mask, which is in an easily accessible location so the diver can open the Switch Block valve unaided and in nil visibility conditions. It is a diver activated switched valve to change the air supply from the main cylinder (switch in horizontal position) to the bailout (turn switch 90 deg, clockwise to the vertical position).
