Abstract
A micro relay is provided including a movable contact, a stationary contact, and a ground contact opposed to the movable contact. In an operating state, the movable contact touches the ground contact when the movable contact separates from the stationary contact. In a non-operating state, the movable contact remains separated from the ground contact so that the movable contact does not stick to the ground contact. Since no parasitic capacitance is formed between the stationary contact and the movable contact, the isolation property of the micro relay is improved.
