A board of a controller of a load drive device includes: wiring layers provided on front and rear surfaces and inside thereof and ground layers provided inside thereof. Each wiring layer is divided into: a first region in which a drive circuit is provided; and a second region in which a control circuit is provided. A first ground layer including a first ground pattern for a circuit which is electrically connected to a wiring pattern of each wiring layer is divided into: a third region which overlaps with the first region in a thickness direction, and in which the first ground pattern for a power system electrically connected to the drive circuit is provided, and a fourth region which overlaps with the second region in the thickness direction, and in which the first ground pattern for a control system electrically connected to the control circuit is provided.

Load drive device

A lid has a fixing surface to be fixed to a metal board so that a metal surface, equipped with no components, of the metal board is in contact with the fixing surface, a through bore provided in laterally close proximity to the fixing surface and exposing mating parts of an external connector with which harnesses are mated, a fixing edge provided around the through bore and fixed to a housing of the external connector; and fixing pedestals projecting from a circumference of the fixing surface and fixed to the control board. A direction of connecting power supply terminals of the external connector to the metal board is a direction being perpendicular to the metal board. A direction of connecting the control board to signal terminals of the external connector is identical to the direction of connecting the power supply terminals to the metal board.

Electric motor control apparatus

A switch device has a case, an operation knob disposed above the case, and a connector disposed under the case. The connector has connection terminals and a housing supporting the connection terminals, the housing being formed with an opening portion from which the connection terminals are led out. The case is provided with an impervious wall extending downward from the case so as to be opposed to both side surfaces of the housing parallel to a leading-out direction of the connection terminals. The impervious wall is arranged across a gap from each of the both side surfaces of the housing.

Switch device

A switch device has a casing, a tubular portion provided on the casing, an upper surface and a lower surface of the tubular portion being opened, a support shaft provided in the tubular portion, a manipulation knob attached to the tubular portion such that an opening in the upper surface is covered therewith, the manipulation knob being turned about the support shaft by manipulation, a first hitting portion provided in the manipulation knob, a first hit portion provided in the tubular portion, the first hitting portion hitting the first hit portion when the manipulation knob is turned to reach a limit of an operating range of a turning operation of the manipulation knob, and a second hitting portion provided in the manipulation knob independently of the first hitting portion.

A switching apparatus includes a case, an operation shaft whose one end outwardly projects from inside of the case and which is provided at its central portion with a flange, a support member which supports the flange such that the operation shaft can rock and rotate, an operation knob mounted on one end of the operation shaft, a first contact which is switched when the operation knob is pushed to move the operation shaft, a second contact which is switched when the operation knob is rotated to rotate the operation shaft, and a third contact which is switched when the operation knob is rocked to rock the operation shaft. The support member comprises a first support member which supports the flange from the operation knob in a state where the operation shaft penetrates the first support member, and a second support member which is disposed inside of the first support member and which supports the flange from the opposite side from the operation knob in a state where the operation shaft penetrates the second support member. The first contact is disposed in the vicinity of the operation shaft on the opposite side from the operation knob of the support member adjacent to the second support member, and the first contact is switched by the second support member which follows the operation shaft and moves when the operation knob is pushed.
