Description

[Detailed description of the invention] The present invention is a switch switching system in which a changeover switch and an operation knob, which are separated by a step, are connected by an operation lever or the like, and the changeover switch can be remotely operated by the operating child. It is related to the device.

In other words, in general, in car radios, etc., the operation descendants are installed at the bottom of the front panel at the front of the device, but due to the structure of various changeover switches, etc., consideration is given to reducing lead wires and workability. In some cases, they were mounted on a board above the rear of the device body, away from the front panel.

Therefore, when the change-over switch is remotely operated by such an operating child, the change-over switch itself is provided with a spring for returning the change-over element, and there is a considerable step difference between the change-over knob and the change-over switch. A large bending moment is applied to the operating lever and the connecting rib that connect the switch, resulting in deformation, which has the disadvantage that the changeover switch cannot be completely switched.

The present invention has been developed in view of this point, and is an attempt to make it possible to smoothly and reliably perform the switching operation of the changeover switch using an extremely simple structure.

An embodiment of the present invention will be described below with reference to the drawings.

1 in the figure is a switch 2 that switches and slides in the direction of arrow A.
.

Further, since the changeover switch 1 is a normal button-button type switch, it is provided with button-button locking mechanisms 5, 5' for locking the changeover elements 2, 2' at the switching sliding positions, respectively. However, those switches 2,
It is assumed that the return springs (not shown) for returning 2' to their original positions have been removed.

Reference numeral 6 denotes an operating knob 6 which is slidably operated in the direction of arrow A using a guide rib 10 integrally formed with a back plate 9 fixed to the mechanism main body 7 with screws 8 as a guide. is attached to one end of the operating lever described later.

11 is slidably attached to the substrate 12, and
The operating lever is always biased in the opposite direction of arrow A by a return spring 13, and the operating knob 6 is attached to one end of the operating lever 11 as described above, and the connection described later is attached to the other end. The ribs are screwed on.

14 is a connecting rib made of synthetic resin that is screwed onto the rear end of the operating lever 11 via a screw 15, and the connecting rib 14 has an engagement recess 16 that engages with the switch 2 of the changeover switch. In the engagement recess 16, protrusions 18, 18 that engage with the notches 17, 17 of the switching element 2, respectively, and a stepped part 19 that abuts the lower surface of the switching element 2 are provided. There is.

Therefore, the other switch 2 of the changeover switch 1 is also connected to another operating knob via an operating lever, a connecting rib, etc. (not shown).

Therefore, when the operating knob 6 is slid in the direction of the arrow A, the changeover switch 1 is operated smoothly and reliably via the switching element 2, the connecting rib 14, and the operating lever 11.

Note that the switching operation force applied to the changeover switch at this time is very small because the switching element is not provided with a return spring, and therefore the bending moment applied to the operating lever and the connecting rib is also very small. The changeover switch can be reliably changed over without the connection rib trying to escape greatly from the changeover element (largely warping backward) when the operating child is operated.

In addition, due to such a small bending moment, the connecting rib tries to escape slightly (that is, curves backward), but the step provided in the engagement recess comes into contact with the lower surface of the changeover lever of the changeover switch. Preventing escape.

Therefore, when the operating knob is pressed, the changeover switch is smoothly switched to the locked state, and when the operating knob is pressed again, the changeover switch is unlocked and returned to its original state by the return spring of the operating lever.

As described above, according to the device of the present invention, the change-over switch and the operation pedigree, which are separated by a step, are reliably connected by the operation lever and the connecting rib with an extremely simple configuration, and the change-over switch can be remotely operated by the operation pedigree. This has the effect of allowing the process to be carried out extremely smoothly and reliably.
