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.
