Oxygen pressure regulators with semi-automatic network power switching and a light and sound pressure drop alarm (hereinafter referred to as the switch), are designed to reduce high pressure coming from two sources: main and backup, to a set value and uninterrupted supply of oxygen to the low pressure network due to automatic switching between sources. The switch is equipped with an alarm with a visual indicator and an audible signal. The power source can be cylinders or manifolds, the collectors of which must be equipped with shut-off valves.
