INPUT APPARATUS FOR ELECTRONIC DEVICE

摘要

An input device for an electronic device includes a floating prevention mechanism that prevents a physical key from being rocked. The input device may include a case, a body that is partially exposed to the outside of the case, a key base that is made of a soft material and coupled to a lower surface of the body, a switch that is positioned below the key base and generates an electrical signal when pressed by a force that is equal to or larger than a predetermined magnitude, and a substrate on which the switch is mounted. The key base may include a pressing protrusion that is formed on a bottom surface of the key base and presses the switch, and a floating prevention unit that is made of a soft material and formed at opposing sides of the key base with respect to the pressing protrusion. The floating prevention unit supports the body to prevent the body from being rocked.
