Description

[Detailed description of the invention] The present invention relates to switch operating devices such as push button switches used in radio receivers and other equipment, and the purpose is to provide an excellent switch operating device with a simple configuration and less tilt of the knob. It is something.

2. Description of the Related Art Generally, a push button switch operating device constructed as shown in FIG. 1 is known.

In Figure 1, 1 is the cabinet, 2 is the cabinet 1
3 is an operating knob inserted into and out of the through hole 2, 4 is a flange formed at the rear end of the operating knob 3, and 5 is an inner surface of the cabinet 1. A locking piece 7 is integrally formed and has a locking pawl 6 at its tip; 7 is a plate spring attached to the inner surface of the cabinet 1 whose tip presses the flange 4 of the operating knob 3 in the direction of arrow A; 8 is a leaf spring of the cabinet 1; A boss integrally formed on the inner surface of, 9 is an angle 10
12 is the operating shaft of the switch 9; 13 is fitted onto the operating shaft 12, and the operating shaft 12 is moved in the direction of arrow B by a force stronger than the leaf spring 7. This is a biasing spring.

By the way, in this type of switch operating device that has been used conventionally, a flange 4 is formed on the operating knob 3, and a leaf spring 7 is attached to the flange 4.
If the through hole 2 formed in the cabinet 1 for inserting the knob is even slightly larger than the operating knob 3, the operating knob 3 may be tilted significantly by the leaf spring 7 as shown in the figure. It was extremely inconvenient.

This proposal eliminates the above-mentioned conventional drawbacks,
To provide an excellent switch operating device with a simple configuration and less tilt of an operating knob.

Hereinafter, the switch operating device of the present invention will be explained with reference to drawings of one embodiment.

2 to 4 show one embodiment of the switch operating device of the present invention, and the same reference numerals as in FIG. 1 in the figures indicate the same components as in FIG. 1.

Reference numeral 14 denotes a rib having a semicircular cross section formed on the flange 4 of the operating knob 3.

The rib 14 is formed in a direction passing through the central axis of the operating knob 3 and perpendicular to the central axis, and the tip of the leaf spring 7 is configured to abut only on this rib 14.

In the embodiment described above, the operating knob 3 is urged in the direction of arrow A by the leaf spring 7, and at the same time is pressed in the direction of arrow B by the spring 13, so that it protrudes more than the cabinet 1 in a steady state.

If the operating knob 3 is pressed in the direction of arrow A in this state, the operating shaft 12 of the switch 9 will also be moved in the direction of arrow A, so that the switch 9 will be pressed.

By the way, in this case, in the conventional switch operation device, the operation knob 3 was very easy to tilt, but according to the above embodiment, a rib 14 is formed on the flange 4 of the operation knob 3. Since the operating knob 7 is configured so as to be in contact with the operating knob 3, no extra tilting force is applied to the operating knob 3, and the operating knob 3 can always be maintained in a tilted state as shown in FIGS. 2 and 3.

As is clear from the above embodiments, according to the switch operating device of the present invention, since no extra tilting force is applied to the operating knob, the tilting can always be minimized, which is extremely advantageous in practice.

Claims (1)

[Scope of utility model registration request] An operating knob with a flange at the rear end is inserted into and out of the through hole formed in the cabinet for inserting the knob, and the rear end of the operating knob is attached to the switch installed in the cabinet by means of a separately provided leaf spring. In a switch operating device configured such that the switch can be operated by operating the operating knob by contacting the operating shaft, a rib is formed in the center of the front surface of the flange of the operating knob, and the rear end surface of the operating knob is A switch operating device configured such that the leaf spring that is brought into contact with the operating shaft of the switch is brought into contact only with the rib.
