1 Excellent Material: Dual power switch is made of excellent PC flame retardant plastic material with good insulation, high temperature resistance, aging resistance, safety and reliability. The use of silver contacts can greatly improve the conductivity and service life of the switch. 2 High Sensitive Response: When there is an abnormality in the normal power supply, the standby power supply works immediately, and millisecond level switching achieves the effect of continuous power supply, ensuring the continuity, reliability, and safety of power supply. 3 Two Operation Modes: Dual power switch can be operated automatically or manually, with millisecond switching without power failure, compact structure, reliable transmission, convenient installation and maintenance, and long service life. Widely used in various situations where continuous power outages are not allowed. 4 Standard Rail Installation: The dual power automatic switch is a miniature household power switch that is mainly used to test whether the main power supply or standby power supply is normal to ensure the continuity, reliability, and safety of the power supply. This switch is specially designed for track installation and is dedicated to PZ30 power distribution box. 5 Widely Used: Automatic transfer switches switch to standby power supply when power failure occurs, and switch to main power supply when power failure occurs. They are suitable for emergency power supply systems with a 50 or 60 Hz AC rating of 230 V, and are widely used in various places where continuous power failure is not allowed, such as factories, shopping malls, seedling farms, and other places.
