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.
Claims8
A micro relay, comprising:
- a movable contact;
- a stationary contact;
- and
- a ground contact opposed to said movable contact;
- wherein
- in an operating state, said movable contact touches said ground contact when said movable contact separates from said stationary contact;
- and
- in a non-operating state, said movable contact remains separated from said ground contact.
A micro relay, comprising:
- a movable plate that can rotate involving torsional deformation of a supporting spring unit provided at a center of said movable plate;
- wherein
- said movable plate further comprises two flap units and two leaf spring units, each flap unit being formed by a slit, and the leaf spring units being positioned one on each side of said movable plate, each said leaf spring unit supporting the corresponding flap unit to said movable plate;
- a movable contact and another contact are provided on a free edge side of the corresponding flap units;
- and
- said movable contact moves with a rotation of said movable plate involving elastic deformation of said supporting spring unit and with a rotation of said flap unit involving elastic deformation of said leaf spring unit.
