Actuating Positions

When installing recessed and surface mount contacts, magnet position

is very important. The switch and magnet must always be parallel or

end to end, and never in a ‘T’ configuration.

Gap Distance

Gap distance is a combination of the horizontal and vertical plane

separation of the switch and magnet. Example: if a recessed magnet

is 1/4” off the centerline of the switch, the make gap is reduced by

1/4”
