Abstract
The electronically switchable MEMS valve includes a housing formed from soft magnetic material and defining a fluid flow path therethrough. A magnetic field generating member is mounted within the housing and connected to a source of electrical power. A MEMS valve portion is mounted within the magnetic field generating member, has a valve closing member movably mounted therein, and defines a portion of the fluid flow path therethrough. The valve closing element is movable between a closed position wherein the fluid flow path is blocked, and an open position wherein the fluid flow path is not blocked. When an electric current is removed from the magnetic field generating member, the valve closing element is configured to move to and remain in the one of the closed position and the open position to which the valve closing element is the closest when the electric current is removed.
