  • Control-key mechanism having improved operation feeling
    Patent number: 5525770
    Abstract: A tilting member has a force bearing portion to which operating force is applied, and a supported surface. A supporting member has a supporting projection with which the supported surface of the tilting member may come in contact. When the operating force is applied to the tilting member, the tilting member tilts with respect to the supporting member. The supporting member supports the tilting member at a supporting point where the supporting projection of the supporting member is in contact with the supported surface of the tilting member, about which supporting point the tilting member tilts. The tilting of the tilting member, with respect to the supporting member, establishes a predetermined electrical contact.
