Wall Mount - Placement Options
To install the switch, either set it on its four rubber pads and place it on a flat surface, or mount it on a wall using the wall-mount slots on the
bottom panel of the switch.
To use the wall mount option, follow these steps:
Step 1 : Attach two screws to the wall such that the wall-mount slots of the switch lineup with the two screws.
SF110D-05 - The screws should be 1.7 in (43 mm) apart.
SF110D-08 - The screws should be 2.5 in (63.5 mm) apart.
SF110D-16 - The screws should be 2.5 in (63.5 mm) apart.
The wall-mount slots are two criss-cross slots on the bottom panel of the switch.
Step 2: Maneuver the switch to insert the screws into the two wall-mount slots.
