Document Type and Number:
WIPO Patent Application WO/2017/116069
Kind Code:
The present invention relates to an actuator for a high-speed switch. The frame of the present invention is formed by a frame (110), and the frame (110) consists of multiple mounting plates (112) and columns (114). The mounting plates (112) have parts installed thereon or movably supported thereby. The columns (114) maintain the space between the mounting plates (112). A driving unit (116) is installed so as to pass through a part of the mounting plates (112), and the driving unit (116) is provided with a first driving plate (122) and a second driving plate (124) on a driving shaft (118). A first coil unit (126) is provided on the mounting plate (112) so as to face the first driving plate (122) and generates the movement of the first driving plate (122) at the time of an opening operation. A permanent magnet (128) is installed on one of the mounting plates (112) so as to face the second driving plate (124), and an elastic member (132) is installed on the mounting plate (112) that faces the mounting plate (112) having the permanent magnet (128) installed thereon, so as to provide force for the movement of the second driving plate (124). The permanent magnet (128) also allows the driving unit (116) to perform a making operation and maintain a making state. Further, the permanent magnet (128) and the elastic member (132) are jointly in charge of the force for keeping the driving unit (116) in the making state; thus, if the driving unit (116) deviates from the influential area of the permanent magnet (128) when the opening operation occurs, the opening operation is quickly carried out.
