Feature: 1. 2 TYPES OF OPERATION: The changeover switch can be operated automatically or manually, milliseconds switching without power failure, widely used in various situations where continuous power failure is not allowed. 2. SUPER FAST SWITCHING: When the normal power supply is abnormal, the standby power supply works immediately, with millisecond switching to achieve the effect of non stop power supply, ensuring the continuity, reliability and safety of the power supply. 3. SILVER CONTACT: The contacts in the automatic transfer switch use silver contacts, which can greatly improve the conductivity and service life of the product. 4. DIN RAIL MOUNTING: Dual power automatic switch designed for rail mounting, specifically for use in the PZ30 distribution box to test whether the main or standby power is working properly. 5. PC HOUSING: The changeover switch is made of PC flame retardant plastic material with good insulation, high temperature resistance, anti aging, safe and reliable.
