A magnetic base can be used on any surface that is magnetic and can be placed in the following positions:
Vertically
The base is in contact with a flat surface.
Horizontally
The base is placed on a surface, using the reverse magnetic edge to hold it in place.
Inverted
The base is placed inverted on a magnetic surface
At an angle
The magnetic base is placed on a rounded surface, using the V-shaped cut-out to hold the base in place, on a surface which is at an angle.
On some magnetic bases the reverse side to the switch side has a magnetic face, giving the base another possible surface to use, if the underside face is not suitable for the application.
