Works for trailer lighting
Works perfectly for my enclosed trailer lighting application. Switches from AC plug to battery. As reviews states there is short delay but does not impact what I am using it for. Price right!

Not a bad little switch for low power usage

Works great.
I used this to rewire and power a small dehumidifier in my rv. It’s used to transfer power to the dehumidifier from lithium battery to shore power when storing the rv. Works great to have full time dehumidification of rv and being able to use it when rving without having to use my inverter.

Nice
Nice little relay. I needed to be able connect to three different power sources. The onboard battery, external 12v, and 120v to 12v power supply. Used two relays chained together. My wire configuration automatically starts with battery. Jumps to 12v external power, then to the 120v power supply no need for switches. Looks well made and small in size.

Works as advertised. Very slow switching though.
Does what it needs to do, it switches power between sources. It does the switch slowly though. The switch is slow however and causes my alarm panel to lose power before the switch is complete. The amazon page warns of this, but i was hoping to bridge the time gap with capacitors. I tried a capacitor bank of 80,000uF until I gave up on that idea. I'll buy a different transfer switch for my alarm panel. My alarm panel draws between 1 and 2 amps at 12v.

Works great! When power switches over, there is a power interruption for about a second.

説明書などは付属せず、本体だけが届きます。説明書がなくとも、電子工作の技術がある人だと機能は理解できるものですね。DCの入力先を リレーで切り替えるもので、常時使っている電源が何らかの理由で落ちると、それを検出して スタンバイしている電源（通常バッテリ）に切り替えるものですね。 リレーを動かす電源はおそらくスタンバイ側から取っているはずです。
