Abstract
Description
One aspect of the present invention relates to an electronic switchgear, and more particularly to a miniaturized electronic switchgear.
The electronic switchgear is a kind of electrical contact switch for supplying or stopping current, and can be used in various industrial equipment, machines, vehicles, and the like. The electronic switching device includes a fixed contact point and a movable contact point, and includes an electric actuator for driving the movable contact point to enable the open / close control of the fixed contact point by an electrical signal.

Miniaturization is required for the above-mentioned electronic switchgear to be used in a mobile body such as an automobile.
According to one aspect, a miniaturized electronic switchgear is proposed.
According to an embodiment of the present invention, an electronic switch including a fixed contact, a movable contact contacted to and separated from the fixed contact, and a driving unit for driving the movable contact to move up and down may include a driving part spaced apart from the fixed core and the fixed core so as to move the vertical contact. A movable core horizontally moving with the fixed core in the vertical direction, and a displacement drive unit connected to the movable contact and the movable core to convert the horizontal motion of the movable core into the vertical movement of the movable contact.
According to the present invention, miniaturization of the electronic switchgear can be achieved.
