Patent number: 6765164Abstract: A push button designed such that it is not damaged or broken even when an excessive external force is applied. The push button includes a control panel having a seat depression and a switch controlling a function. A button unit is seated in the seat depression so as to be movable by a predetermined distance. A push unit passes through the seat depression and moves by a force transmitted from the button unit to push the switch. The push button also has first and second springs having different spring constants. When a normal external force is applied, the second having a smaller spring constant, is elastically compressed to turn the switch on or off. When an excessive external force is applied, the first and second springs are elastically compressed to absorb external force, thus preventing components, such as the switch, from being damaged or broken.Type: GrantFiled: April 24, 2003Date of Patent: July 20, 2004Assignee: Samsung Electronics Co., Ltd.Inventors: Hyun-Mu Lee, Ki-Su Lee
