Title:
CONTACT MODULE, CONTACT DEVICE, ELECTROMAGNETIC RELAY MODULE, AND ELECTRIC INSTRUMENT
Document Type and Number:
WIPO Patent Application WO/2019/103063
Kind Code:
A1
Abstract:
Provided are a contact module, a contact device, an electromagnetic relay module, and an electric instrument in which the connection state between a movable contact and a fixed contact can be stabilized. This contact module (91) comprises a pair of contact devices (1). The pair of contact devices (1) each includes a fixed terminal (31, 32) and a movable contact element (8). The movable contact element (8) moves between a closed position at which a movable contact is in contact with a fixed contact and an open position at which the movable contact is separated from the fixed contact. During the passage of current, one of the movable contact elements (8) generates a magnetic field that exerts, on the other movable contact element (8), a force in a direction from the open position toward the closed position. During the passage of current, the other movable contact element (8) generates a magnetic field that exerts, on the one movable contact element (8), a force in a direction from the open position toward the closed position.
