Abstract
PURPOSE:To smooth the key operation and ensure contact input, by specifying the shape of the part corresponding to the key of elastic switch member. CONSTITUTION:The shape of the part of an elastic switch member 40, assembled into a case upper case band 20 to together with stopper member 30 and others of key 10, which corresponds to the key 10 is fashioned in a peaked elliptical form consisting of a hill-shaped knob 42 and an elliptical top 43. When the key 10 is pushed, the end part 12 pushes down the elastic switch member 40 until the collar part 11 abuts against the stopper member 30, so that the switch contact 41 is made to contact with an electrode 51 of a module 50. When the key 10 is released, the key 10 restored the original position due to the recovering power of the elastic switch member. And, because the shape of the part corresponding to the key 10 is a peaked elliptical form, the elastic switch member 40 operates securely.
