Abstract: A touch pad module for controlling the movement of a cursor includes a plate, two resilient arms coplanar with the plate, each of the resilient arms having a free end part opposite to an end formed integrally with the plate, each of the resilient arms being bendable to permit the free end part to resiliently move away from the plane of the plate, a touch control region formed at a front side of said plate, a control circuit unit disposed opposite to the touch control region at a rear side of the plate, and a switching unit provided on a rear side of each of the resilient arms and electrically connected to the control circuit unit. The switching unit has a movable contact member projecting resiliently from the rear side of the corresponding one of the resilient arms.
