George Risk Industries (G.R.I.) 140T-12-B | Recessed Switch Set, Spdt, 1/2" Gap, With Mm-9

The 120T/4473 requires that a 3/4" hole be drilled for the switch and 3/8" hole for the magnet.

The 3/4" switch mounting is desirable since the extra wire and connections can be more easily inserted into the larger hole for concealment.

Also, should the need arise for testing or replacement, it would be easy to pull the switch, extend the extra wire and access the original connections.
