Guys there is no battery as I understand after reading some internet material. The transmitter uses a snap spring mechanism and an induction coil to convert the button press to electrical energy to do the transmission.

Does it work when there is no electricity in the house?

[darkdjshow]

The product still cannot be set. Pls how to connect. Ty

I have lost my door bell switch what can I do?

[aprilthunder]

How can it be self-powered when you still have to plug it into a wall outlet?

[Kidsworld]

Its not self powered . The switch required 24 Volt battery. It cost most than the wired bell. Because
You have to change battery every 3 to 6 month.

Self powered means there’s a battery hidden 😂😂
