ABSTRACT:
Disclosed herein is a mounting structure of a reed switch in an eddy-current-type indicator which can realize to lessen an operation vibration sound of the reed switch. The mounting structure comprises a housing, a magnet rotatably provided in the housing, a pair of terminals mounted on the housing, a reed switch for detecting the number of the rotation of the magnet by generating pulse corresponding to the rotation of the magnet, the reed switch having a pair of leg portions electrically connected to the terminals, respectively, and cushion members for preventing vibration generated in the reed switch when it is operated from being transmitted to the housing and terminals. The cushion members elastically contact with the leg portions of the reed switch, so that the operation vibration is absorbed by the cushion members.
