A rocker switch device is provided in which a pair of shaft portions are projectingly provided on mutually opposing faces of extremity portions of a pair of side wall parts of a switch case, the pair of shaft portions being aligned on the same axis as each other, a bearing hole is formed in an operating knob so as to extend therethrough, the pair of shaft portions being rotatably fitted into the bearing hole, a projecting portion is provided on an outside face of the pair of side wall parts, the projecting portion being pressed into contact with the support body to thus prevent rattling of the switch case, and a support pin is fitted into the bearing hole, opposite ends of the support pin abutting against extremities of the pair of shaft portions respectively. Such arrangement prevents switch malfunctioning, and restrains deformation of the side wall parts.

An operation feel imparting type input device includes a fixed part, a rotating body rotatably supported by the fixed part, a rotatable operation knob fixed to the rotating body, a rotation angle detection unit configured to detect a rotation angle of the rotating body, a brake application unit configured to apply a braking force to the rotating body, a torque application unit configured to apply a torque to the rotating body, a control unit configured to control the brake application unit and the torque application unit, and an operation torque detection unit configured to detect the magnitude of an operation torque applied to the rotating body. When the rotating body is rotated from an endstop, brake release is performed according to the magnitude of the operation torque.

An operating mechanism including a number of biasing elements and a number of linkage members is provided. The linkage members are operatively coupled to each other and each are movable between a second configuration, an initial tripped configuration, a rebound configuration, and a final tripped configuration. The biasing elements are operatively coupled to the number of linkage members and bias the number of linkage members to the final, first configuration. A stop member is coupled to one of the linkage members. The stop member moves with the associated linkage member. The stop member is positioned to contact a stop surface when the linkage members are in the rebound configuration. Contact between the stop member and the stop surface substantially arrests the motion of the linkage members.

A secure, reliable and simplified control mechanism for operating an inverter is provided. In particular, a mechanical switch is used for connecting a local grid with a public grid and for disconnecting the local grid from the public grid. The mechanical switch comprises an intermediate position. Each time when the switch is in this intermediate position, the inverter is immediately shut down in a fast shutdown operation.
