Title:
MICRO MACHINE SWITCH
Document Type and Number:
Japanese Patent JP2002100276
Kind Code:
A
Abstract:

To provide a small machine type switch and a relay having a contact with high reliability.

A holding electrode having the same shape as the deflection shape of a beam is provided to keep the beam's deflection shape by an electrostatic force. The contact surfaces of the contacts are made to be contacted each other with a contact angle close to 0 as much as possible for a larger contact area. Since the contact is kept by the electrostatic force of a uniformly distributed load, high quality contacts in which a stiction problem is reduced, with a lower contact resistance can be provided.
