    摘要: A method of fabricating a MEMS switch having a free moving inductive element within in micro-cavity guided by at least one inductive coil. The switch consists of an upper inductive coil at one end of a micro-cavity; optionally, a lower inductive coil; and a free-moving inductive element preferably made of magnetic material. The coils are provided with an inner permalloy core. Switching is achieved by passing a current through the upper coil, inducing a magnetic field unto the inductive element. The magnetic field attracts the free-moving inductive element upwards, shorting two open conductive wires, closing the switch. When the current flow stops or is reversed, the free-moving magnetic element drops back by gravity to the bottom of the micro-cavity and the conductive wires open. When the chip is not mounted with the correct orientation, the lower coil pulls the free-moving inductive element back at its original position.

    摘要: A MEM switch is described having a free moving element within in micro-cavity, and guided by at least one inductive element. The switch consists of an upper inductive coil; an optional lower inductive coil, each having a metallic core preferably made of permalloy; a micro-cavity; and a free-moving switching element preferably also made of magnetic material. Switching is achieved by passing a current through the upper coil, inducing a magnetic field in the coil element. The magnetic field attracts the free-moving magnetic element upwards, shorting two open wires and thus, closing the switch. When the current flow stops or is reversed, the free-moving magnetic element drops back by gravity to the bottom of the micro-cavity and the wires open. When the chip is not mounted with the correct orientation, gravity cannot be used. In such an instance, a lower coil becomes necessary to pull the free-moving switching element back and holding it at its original position.
