Abstract
An apparatus and method for actuating and deactuating an electro-mechanical switch utilizing an energy-storing actuator is disclosed. An electro-mechanical switch can be configured to include an (internal or external) lever. A first magnet having a first magnetic field thereof is generally located on the (internal or external) lever of the electro-mechanical switch. A second magnet having a second magnetic field thereof is generally located on an energy-storing actuator, such as a bi-metal coil, wherein the second magnetic field of the second magnet opposes the first magnetic field of the first magnet to form an opposing magnetic force thereof in order to actuate and deactuate the electro-mechanical switch.
