When the main operating body (1a) is in a free state with the cover body (2) attached to the box main body (1) and the actuator (31) and the inner top of the auxiliary operating body (1b) are in contact with each other. Either the contact is made with a very small gap, or the actuator (31) and the auxiliary operating body (1b) do not come into contact with each other when the switch (3) is not operated. Since the auxiliary operating body (1b) and the main operating body (1a) are in point contact with each other at the tops of the protruding spherical surfaces, the click operation feeling when operating the actuator (31) is changed by the main operation. It will remain in the body (1a). The planar shape of the auxiliary operating body (1b) is made elliptical, and the concave portion (1b) is formed.
8) has a flat shape suitable for this,
In (18), the posture of the auxiliary operation body (1b) does not change. In addition, the auxiliary operating body (1b) is an injection-molded product of a synthetic resin. In this case, a small protrusion of a gate mark remains on the periphery of the body portion.
It is formed on the inner peripheral surface of 8). Therefore, even if there is a minute protrusion of the gate mark, it moves in the notch groove, and the operation of the auxiliary operating body (1b) in the concave portion (18). Smoothness is ensured. In addition, the positioning accuracy with respect to the posture around the movement axis is high. [Attaching of the main remote controller] The main remote controller having the above-mentioned structure has a rectangular frame-shaped mounting bracket (4) shown in FIG.

[Actual Operation] In the above-mentioned mounted state, the switches (3) and (3) can be turned on and off by operating the main operating bodies (1a) and (1a). The switch (3) changes a contact from a non-contact state to a contact state by reversing a built-in leaf spring from one arc state corresponding to OFF to another one arc state corresponding to ON. In this inversion operation, a click operation is performed. Therefore, when the switch (3) is directly depressed, the actuator (31)
This gives an operational feeling at the moment when the leaf spring performs the reversing operation. An auxiliary operating body (1b) contacting the actuator (31) and a main operating body (1a) contacting the auxiliary operating body (1b)
Means that each of these contact points is a point contact between the spherical tops and a point contact between the plane portion and the spherical top, and
Since the auxiliary operation body (1b) is held in a free state in the recessed portion (18) of the front plate (15) of the box main body (1), the main operation body (1b)
The operation feeling when a) is operated is almost the same as that when the actuator (31) is directly operated. Therefore, the click operation feeling remains as it is during the operation. By the above operation, when the switch (3) is turned on, the light emitting section (32) is in a light emitting state, and this light is transmitted to the main operating body (1) via the auxiliary operating body (1b) having light collecting and scattering properties.
a) reaches the display print layer (11) on the back side, and this display print layer (11)
Scatters and emits light almost uniformly over the entire region. This scattered light can be seen through the transparent synthetic resin constituting the main operation body (1a) from the outside.
Therefore, the light emitting display section has a transparent feeling (clear feeling), and provides a display with sufficient brightness. In addition, the auxiliary operation body
Even if the entirety of (1b) is a transparent body, the transparency and brightness of the display are the same. When the box main body (1) is mounted by the mounting bracket (4) described above, the box main body (1) with the cover body (2) is supported at the upper and lower two points and the left and right key-shaped recesses (19) are provided. ) (19) also locks in the retaining state, so that the mounting state of the box main body (1) is stabilized. further,
