  • Patent number: 11037734
    Abstract: A mounting structure minimizes the influence of displacements, along a length direction of a resistor, in mounting positions of capacitor electrodes on the electrical characteristics of a circuit including a parallel circuit composed of a capacitor and the resistor. The capacitor has first and second electrodes, which respectively include first and second side surface portions disposed in parallel to a length direction of the resistor. The resistor has a first resistance body corresponding to the first side surface portions and a second resistance body corresponding to the second side surface portions that are separately disposed along the length direction and connected in series via a wire, and is mounted so that the first resistance body is positioned directly facing the first side surface portions and the second resistance body is positioned directly facing the second side surface portions.
    Type: Grant

  • Patent number: 8981759
    Abstract: A multimeter includes: a rotary switch which selects a measurement function; a common terminal hole into which a connector of a test probe is inserted; selection terminal holes into which the connector of the test probe is selectively inserted; and shutter plates which selectively open the selection terminal holes. The rotary switch includes convex portions. The shutter plate includes a hole corresponding to the common terminal hole so that the shutter plate rotates by using the center of the common terminal hole as the rotation axis and includes a concave portion engageable with the convex portion so that the shutter plate rotates to open the selection terminal holes by the movement of the convex portion. The shutter plate includes a concave portion engageable with the convex portion so that the shutter plate opens and closes the selection terminal hole by the movement of the convex portion.
