The magnetic switch assembly of an embodiment generally comprises a switch housing coupled to and/or adjacent to a magnet housing. The switch housing may be coupled to, for example, a door frame, a window frame, or other substantially fixed location. The magnet housing including at least one magnet may be coupled to, for example, a door or other substantially mobile location adjacent to the switch housing. The proximity to or distance from the magnets in the magnet housing may actuate one or more reed switches within the switch housing to open and/or close a circuit and/or otherwise generate a signal that may be communicated to, for example, a security system to detect whether the door is open or closed.
