FYI anyone - I'm liking this Zigbee In-Wall Switch. MS-104Z. It appears to be very well made.
I cracked one open. Take a look. There's a wee TUYA Zigbee board inside....
And discovered its switched contacts are "Dry Contacts". That is they DO NOT have voltage on them. This makes them useful in situations where you might want to switch "other" circuits. The switch contacts are completely isolated.
When you DO want to switch something like a light fixture, then you need to place an external jumper wire between the external "L1" and "L" terminals.
S1 is the switch wire
Lout is one side of the relay (Load)
L1 is the other side of the relay (can be linked to L)
L are the Live terminals
N is the Neutral terminals
I like the fact that they've underrated the device to 10Amps even though there's a 15A relay inside. That's good to see. All the caps are 105c as well
