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, reliability and safety of power supply. The dual power automatic switch is suitable for emergency power supply systems with 50 or 60Hz and rated 400V AC. A TS has the characteristics of solid structure,reliable conversion,convenient installation and maintenance and long service life It is widely used in various occasions where power failure cannot be sustained, and can be operated by electricity or manually. ATS is composed of TSE and controlle
