ABSTRACT:
A magnetic switch has a fixed contact, a movable contact, and a flat, flexible blade supporting the movable contact, and movable between first and second positions in which the contacts are respectively engaged and disengaged. A blade magnet is affixed to the free end of the blade and is movable with it. An actuator is selectively movable to first and second positions corresponding to the first and second positions of the blade. An actuator magnet is positioned on the actuator in facing opposition to the blade magnet. When the actuator is moved to its first and second positions, one pole of the actuator magnet is disposed beyond the position of the blade magnet when the blade is in its respective first and second position. Thus, when the actuator is moved to one of its first and second positions, the blade magnet is repelled by the actuator magnet to drive the blade, with snap action, to the other of its first and second positions.
