Description

Switch structure with different inductance values

The present invention relates to a switch structure having different inductance values, in particular, a difference in the sensing area caused by the irregular shape of the iron core provided inside the switch. When the iron core is disposed in an induction coil, the iron core is generated between the iron core and the induction coil. Different inductance values are used to identify different inductance values by induction to achieve multi-stage control of the switch.

With the continuous advancement of technology, electronic control as small as remote control devices (such as: various remote controls) to control devices (such as: various control machines) has gradually become a tool that people rely on. The various types of electronic control devices still mainly use the control switch as the set input device.

The types of control switches are numerous, such as pressing switches, knob switches, rocker switches, etc., and selecting suitable control switches according to the needs of electronic device design.

As far as the conventional push switch is concerned, the conventional push switch has only a single control function. For example, when the push switch is pressed, the push switch is in the path state; when the push switch is pressed again, the push switch is in the open state. In view of this, if the push switch is used for multi-stage control, more than one push switch must be set to control one function by using each push switch; thus, the number of push switches is increased, which is bound to cause operation of the control device. The interface is cumbersome and also increases the cost of controlling the device.

Therefore, how to make a push switch have the effect of multi-stage control at the same time is the problem that the new type is intended to solve.

The main purpose of the present invention is to disclose a switch structure having different inductance values. The switch of the present invention comprises a pressing mechanism and a core, the pressing mechanism is disposed inside the switch, and the pressing mechanism is provided with a button and an elastic component, and the button is combined with the elastic component. The elastic element can make the button longitudinally reset and move; and the iron core can be combined with the button. For example, the bottom of the button can be extended with a cylinder, and the iron core is provided with a perforation, so that the iron core is coupled to the cylinder of the button through the perforation sleeve, and is driven by the button. The core moves linearly in a longitudinal direction; wherein the core has an irregular shape.

The present invention is characterized in that the sensing area is different by using the iron core in an irregular shape, and the switch can be combined with a predetermined circuit board. The circuit board is provided with an induction coil, and the iron core can be correspondingly disposed on the induction coil. Thereby, the core can generate different inductance values from the induction coil, and then use the induction to identify different inductance values, thereby achieving the effect of multi-stage control of the switch.

In order to make it easier for your examiner to understand the other features and advantages of this creation and the effects achieved by it, this article is combined with the drawings to describe in detail the features and advantages of this creation. The following examples are further The present invention is described in detail, but does not limit the scope of the present invention in any way.

Please refer to the first, second and third figures. The present invention discloses a switch structure with different inductance values. The switch 1 of the present invention comprises a pressing mechanism 11 and a core 12.

The switch 1 is provided with a first opening 10 on the top surface thereof, and the pressing mechanism 11 is disposed inside the switch 1. According to an embodiment, the pressing mechanism 11 includes a button 111, an elastic member 112 and a lower cover 113. The button 111 is combined with the elastic member 112 and disposed inside the switch 1, and is fixedly coupled to the bottom of the switch 1 by the lower cover 113, so that the button 111 can be longitudinally reset and moved inside the switch 1 by the elastic member 112, and the button 111 and the switch 1 are The first opening 10 corresponds to the first opening 10, and the button 111 can extend at the bottom thereof to extend a column 1111. The column 1111 can extend through the lower cover 113 to the outside of the switch 1. The core 12 is coupled to the button 111, and the core 12 is provided with a through hole 121, so that the core 12 is sleeved through the through hole 121 and is coupled to the cylinder 1111 of the button 111. The button 111 drives the core 12 to move linearly in a longitudinal direction. The core 12 has no The shape of the rule, for example, the core 12 has a cylindrical shape at one end and a sloped shape at the other end (as shown in the third figure).

The switch 1 can be coupled to a predetermined circuit board 2, the circuit board 2 is provided with a second opening 21, and the second opening 21 corresponds to the cylinder 1111 of the button 111, so that the core 12 can pass through the second The opening 21 and the circuit board 2 are provided with an induction coil 22 around the second opening 21 to allow the core 12 to pass through the induction coil 22 when passing through the second opening 21.

The present invention is characterized in that the sensing area is different by using the iron core 12 having an irregular shape. When the button 111 of the switch 1 is pressed, the core 111 is driven by the button 111 to pass through the induction coil 22, and the core 12 can be coupled to the induction coil. Different inductance values are generated, and a different control value is sensed by a preset control circuit, and each inductance value can be used as a trigger signal to achieve the multi-stage control effect of the switch 1; thus, avoiding the conventional pressing The switch only has a single on/off control function, which results in the need to set more than one push switch to achieve multi-stage control.

Please refer to the fourth figure, the iron core 12 has an irregular shape. For example, the iron core 12 can be tapered at both ends, so that the iron core 12 can be in the shape of a wine barrel.

Referring to FIG. 5, the core 12 has an irregular shape. For example, the core 12 may have a tapered shape at one end and a cylindrical shape at the other end, so that the core 12 may have a conical shape.
