    • An improved bi-stable electrical solenoid switch comprising a solenoid being wound with coil windings. The solenoid having a central aperture defined therein, and the coil windings, which when engaged by a power source, generates a magnetic field. A magnetic coupling member mounted on the solenoid. A plunger partially disposed in the central aperture for movement into and out of the central aperture. A conductive plate coupled to the plunger and provided with contacts on each end of the conductive plate. The conductive plate configured to electrically engage and disengage the solenoid upon respective application of power to the solenoid. The magnetic coupling member configured to reduce the force needed by the solenoid to remain in an open position when selectively energized for moving and retaining the conductive plate of the plunger against the solenoid for allowing wide operating voltage and reduced operating power.
