You are nearly there.
A typed section is not a test box.
The value option in the text box

The typed section is the definition of a configuration set that matches a
"type" in this case you have defined a config type called "myapp".  By
using a typed section you will iterate over, and display the "key" option
for each config set.
However the second config set of type=myapp named "masterswicth" does not
have a key value, so this will be empty until you save a value

What you really want is

/etc/config/myapp like this:
-------------------------
config 'myapp' 'device'
       option 'key' '1234567890eeefff'
       option 'enable'   '1'
 -------------------------

/usr/lib/lua/luci/model/cbi/mini/myapp.lua like this:
-------------------------
m = Map("myapp", "MyApp")
s = m:section(NamedSection, "device", "myapp")
s:option(Value, "key", "Key", "See admin for your key")
s"option(Flag, "enable", "Enable")
return m
 -------------------------

Also you can make the changes take effect on save using the file
/etc/config/ucitrack
here you list your config file, and which applications it effects, and
which init script needs to be run to reload the configuration
