CONTACT DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/122387
Kind Code:
A1
Abstract:
Provided is a contact device which can reduce abnormal noises by reducing the vibration of a movable contact. The contact device comprises: a pair of fixed contacts (11) which are formed in a cylindrical shape; a movable contact (12) which is formed in a plate shape and is free to move between a contact position which short-circuits the two fixed contacts (11) and a position distant from the fixed contacts; a pressure contact spring (16) comprising a coil spring, one end of which pushes against the movable contact (12), impelling it towards the fixed contact point (11); a holder (17) which supports the other end of the pressure contact spring (16); and a frame-shaped elastic member (40) which is inserted between the holder (17) and the other end of the pressure contact spring (16). The elastic member (40) is deformed by vibrations of the movable contact (12), and after accumulating the vibration energy of the movable contact (12), consumes the vibration energy.
