1.35mm Standard Rail Mounting This dual power automatic switch is a compact, miniature device designed for versatility in household power applications. Its standard rail mounting makes it easy to integrate into control panels for testing whether the main power or backup power is functioning correctly. Millisecond Level Fast and reliable power management is essential. When the main power supply becomes abnormal, the backup power is activated in a matter of milliseconds, helping to minimize downtime for connected devices. PC and Silver Contacts The switch is built with a PC flame-retardant plastic housing to provide insulation and durability. It uses silver contacts to ensure reliable conductivity and stable electrical performance. Two Operation Modes The device supports both automatic and manual operation. This two-mode design offers flexibility to suit different setup needs and testing scenarios.
