Abstract
A method of establishing a contact arrangement for a reed switch. The method increases the number of contact surfaces between the armature and the fixed contact by providing the fixed contact with a contact end that has multiple prongs and positions the armature and the fixed contact so that the prongs surround the armature. The method also adjusts the armature and the fixed contact so that there are prongs that contact the armature when the armature moves from the rest position during switch operation and prongs that provide additional multi-planar contact surfaces for the armature in the event that the armature and the fixed contact prematurely separate during switch operation.
