行えることになる。 As mentioned above, the present invention has a structure in which the contact piece is swingably supported on the fixed part via the lever part, so that the contact piece and the lever part are not forced together with the fixed part. can be smoothly displaced, the elasticity of the compression coil spring always works effectively, a suitable contact state between the opposing contact and the contact piece is maintained, and a highly reliable rotary switch can be obtained. In addition, it has a simple structure in which only three inexpensive parts are assembled together: a fixing part, an integrally formed lever part and a contact piece, and a compression coil spring. In particular, the fixing part and the lever part are When the two are pivotally connected by engagement between the locking hole and the engagement piece, the structure is much simpler than that using a hinge connection, resulting in extremely high assembly workability, high efficiency,
Moreover, it can be mass-produced at low cost. Furthermore, if a protrusion is provided on one or both of the fixed part and the lever part to prevent the compression coil spring from slipping or escaping, the protrusion can be used to prevent the compression coil spring from slipping or escaping during transportation or when the rotary switch is assembled into the main body case. Prevents the compression coil spring from falling off during installation and subsequent complete disassembly.
The rotary switch assembly work can be performed easily and efficiently.
