ABSTRACT:
A dial needle is mounted on a drive shaft of a measuring instrument. The dle includes a body and a support, both mounted on the drive shaft. The body and the support are initially connected in a one-piece construction in which the body is spaced axially from the support. Upon axially moving the body along the shaft to the support, weakened zones break, thereby detaching the body from the support. A pointer on the body is angularly turnable to an indexed position by a peripheral projection and a complementary recess provided on the support and the body.
