1. A method of assembling a latching switch, comprising:

  • (a) attaching a plurality of layers together in a stack, including the steps of;

    (i) including in the stack a layer having a first flexible member formed therein, wherein said first flexible member has a magnetic material and a longitudinal axis;

    (ii) including in the stack a layer having a second flexible member therein;

    (iii) including in the stack a permanent magnet layer that produces a first magnetic field, which induces a magnetization in said magnetic material, said magnetization characterized by a magnetization vector pointing in a direction along the longitudinal axis of the first flexible member, wherein the first magnetic field is approximately perpendicular to said longitudinal axis; and

    (iv) including into the stack a layer that includes a coil capable of producing a second magnetic field to cause the first flexible member to switch between a first stable state and a second stable state, wherein in the first stable state, the first flexible member is in contact with the second flexible member, which flexes in response.
