Abstract:
1. A proximity sensing system comprising: a sensor having at least one switch, said switch including: and a second movable magnet disposed in a switching position to produce a second magnetic attraction force and a second torque about said rotational axis with predetermined magnitude and direction on said movable element to force one of said first end and said second end to move toward said second moveable magnet, forcing said first end of said moveable element to move away from said first permanent magnet, switching said moveable element from said first state to said second state; wherein said movable element returns from said second state to said first state when said second moveable magnet moves out of said switching position, and when said second moveable magnet moves relative to said sensor, said moveable element interacts with a respective one of said contacts based on the position of said second moveable magnet during movement.
