A proximity switch system includes a switch portion, configured to connect and disconnect at least one electrical path, and a magnetically active actuator. The switch portion has a casing formed of a magnetically noninteracting material, at least one electrical contact disposed in the casing, a magnetically active armature member moveable along the casing between a first position and a second position, wherein the armature member contacts the electrical contact when in the first position to connect the at least one electrical path and the armature member being electrically isolated from the electric contact when in the second position to disconnect the at least one electrical path, and a magnetically active biasing member disposed in the casing, wherein the biasing member magnetically interacts with the armature member to bias the armature member in one of the first and second positions. The magnetically active actuator is movable with respect to the switch portion between proximal and distal positions. The actuator magnetically interacts with the armature member when in the proximal position to move the armature to the other one of the first and second positions, and at least one of the armature member and the biasing member include a magnet.
