Abstract

The present invention discloses a rotary switch (10) for coverring a lid (15) on a switch rack (11) containing permanent joint (22). Embedding contact piece (13) contacting to the permanent joint on a rotary operating knob (12), after accepting the contact piece and the rotary operating knob as well as a leaf spring (14) on the switch rack together in order, covering the lid (15) on the switch rack (11) and assembling the rotary switch. The rotary switch uses the switch rack, the contact piece, the rotary operating knob, the leaf spring and the lid as composing component. The rotary switch implements simplification of constitution thereof and miniaturization with low cost, also obtains measurable knocking sense and excellent operating sense.

Description

technical field [0001] The present invention relates to a rotary switch, which is used for mode setting of a digital camera, etc., and particularly relates to a rotary switch which switches contact points by contacting a contact piece with a plurality of fixed contacts and rotating. Background technique [0002] At present, a plurality of fixed contacts are provided on the switch frame (switch base), and the rotary operation knob (rotary plate) used as a switch switch is rotatably installed on the above-mentioned switch frame, and the contact piece (rotor) is installed on the rotary operation knob. , so that the contact piece is in contact with the fixed contact of the switch frame, such a rotary switch is known. [0003] Such a rotary switch has a structure in which recesses are provided at predetermined intervals on the outer periphery of the rotary operation knob, and a ratchet mechanism such as a leaf spring is provided in the recesses. [0004] For example, in Japanese...
