The 120T-12/4473 requires that a 3/4 Inch hole be drilled for the switch and 3/8
Inch hole for the magnet.
The 3/4 Inch switch mounting is desirable since the extra wire and connections can be
more easily inserted into the larger hole for concealment.
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.
Installation is further enhanced by using a smaller 3/8 Inch diameter magnet to avoid
the need to center a larger hole in a 1 Inch to 1 1/2 Inch thick door or window.
This will allow you to offset the magnet should it be required.
The 120T-12/4473 switch set was developed for and should only be used in openings with
wooden or aluminum frames.
