Abstract
In a switch, an elastic member made of elastic material includes a bar section, a conical section at its upper portion functioning as a first deforming section, and a second deforming section at its lower portion. A movable contact in a switch case is pushed with the lower end portion of the second deforming section. A bar section of an elastic element projects through a central hole of a cover fixed to the switch case. In this switch, a pushing force applied to the elastic element deforms the first deforming section elastically, and then the second deforming section deforms elastically, and thus, the switch operates. The switch can absorb fluctuations due to combination of components of an electronic appliance, and stabilize its manipulation feeling through eliminating looseness of an operation button of the appliance.
