In one example, touchpad assembly is disclosed, which may include a bottom cover, a horizontal elastic member flexibly positioned on the bottom cover, a balancing bar disposed on the bottom cover and substantially parallel to the horizontal elastic member, and a metal dome. The metal dome may include a first end fixedly connected to the bottom cover via a first fixture, and a second end to hold the horizontal elastic member and the balancing bar such that the balancing bar is flexibly engaged with the bottom cover. The balancing bar, the metal dome, and the horizontal elastic member may control a flexure of a touchpad when the touchpad is pressed.
