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.

Bi-stable electrical solenoid switch

A power distribution housing including a base, a cover adapted to fit onto the base, a latch member adapted to removably secure the cover to the base, the latch member having a first end pivotably connected to the base and a second end having a latch detent extending therefrom, the latch detent configured to engage a catch in the cover when the latch member is pivoted to a latched position wherein the cover is secured to the base by the latch member, and a locking member coupled to the latch member, the locking member movable between a locked position, in which a locking member extension of the locking member engages a locking member recess in the cover and prevents the latch member from being moved from the latched position to an unlatched position, and an unlocked position in which the locking member extension does not engage the locking member recess.
