Microelectro mechanical system switch
First Claim
1. A microelectro mechanical system (MEMS) switch comprising:
- a substrate;
a signal line formed on the substrate;
a beam deformed by an electrostatic force to electrically switch with the signal line; and
a spring type contact unit formed on the signal line to electrically contact the beam and elastically deformed by an external force.

Abstract
Provided is a microelectro mechanical system (MEMS). The provided MEMS switch includes a substrate; a signal line formed on the substrate; a beam deformed by an electrostatic force to electrically switch with the signal line; and a spring type contact unit formed on the signal line to electrically contact the beam and elastically deformed by an external force. Thus, stability of the contact between the contact unit and the beam is improved. In particular, even when the beam or the contact unit under the beam is unbalanced, the contact unit can elastically contact the beam to obtain a stable electrical switching operation.
