取り付けている。 Conventionally, the channel selection device of a television receiver has a first channel selection device.
As shown in the figure, connection pins 2 corresponding to the desired number of reception channels are planted on a predetermined wiring pattern of a printed circuit board 1. Each connection pin 2 is connected to a channel selection button 3 whose outer periphery is plated with conductive metal.
is inserted and attached through a through hole 4 formed in the support portion 3a.

歪が生じてしまう欠点がある。 In this way, if each connection pin 2 is configured to have individually formed channel selection buttons 3, and the number of channel selection buttons 3 corresponds to the desired number of reception channels, first, select the channel. It takes a lot of man-hours to attach the station button 3 to the connection pin 2, and the workability is extremely poor.
Further, it is extremely difficult to plant all the many fine connection pins 2 upright on the substrate 1 and in a series. Therefore, when the channel selection buttons 3 are attached to the connection pins 2, the channel selection buttons 3 are not aligned, resulting in an extremely unsightly aesthetic appearance.
Furthermore, since the channel selection button 3 and the board 1 are received on the same plane, if the connection pin 2 is not planted correctly, the channel selection button 3 may float off the board 1, or after installation. It has the drawback of causing backlash and dimensional distortion.
そこで、本考案は、上述したような従来の欠点
