Wenzhou Laike Electric Co.,Ltd.
Product overview
The dual power automatic switch is a newly developed miniature household power switch,which is mainly used to test whether the main power supply or standby power supply is normal.When the normal power supply is abnormal, the standby power supply starts to work immediately,which ensures the continuity,rel iabi l ity and safety of power supply,This product is special ly designed for household rail installation and is specially used for Pz30 distribution box.
