Where's the reed switch?

So i’m using these 433mhz sensors. I could have sworn there used to be a tiny reed switch on the board, but i can’t locate it anymore. They break pretty easily as well. I don’t know if this new batch i used, but the weird thing is, a magnet close to it still reports the sensor as opening and closing.

So what’s going on…how can it still report opening and closing without the sensor? i attached two pictures, pretty sure the reed switch is supposed to be between the cutout, and that’s where i would solder my wires as well (for projects to use the sensor, e.g. rain sensor, etc).

Can’t add pictures for some reason, getting Discourse: Invalid access message. Will upload as soon as i can.
