Direction-control switch module for controlling a screen cursor
A direction-control switch module. The module includes a cross-channel disposed in an inner wall of an upper cover and an opposite base respectively, as well as a control set disposed between the upper cover and the base. A common pin and plurality connecting pins extend to the hub or terminals of the cross-channel in the base. An actuation portion includes a center hole being protrusively disposed in the upper cover in an axial line defined by the center of the upper cover and the base. The control set further includes a pushbutton having an axial hole and a spherical portion, a shaft, and resilient members. When force is applied to the shaft to enable the spherical portion in the actuation portion to displace in a specified direction, this enables a depression piece extended from the spherical portion to move downward to depress and contact a connecting pin for output of a distinct direction signal to control displacement of a screen cursor.
