Push-type electrical switch

The present invention relates to an electrical switch, and more particularly to a stroke that can be continuously pressed and continuously maintained while the circuit is connected by pressing, so that the circuit connection effect is more stable and reliable, and a better operational feel can be provided. Push-type electrical switch.

As is well known, an electrical open relationship is a component commonly used in various electrical devices to form a circuit connection of two components in a device; wherein, most of the electrical open relationship provides two structural bodies that can be coupled to each other, so that when two structures are The main body is coupled to the positioning, that is, the circuit connected to the two structural bodies can be normally turned on.

In addition, some electrical open relationships have a structural body fixed in the normal state between the circuits, as shown in the tenth (A) and (B), and an internal force is provided inside the structural body to cooperate with the expected The state-changing conductive element 61, as shown in the embodiment, the first and second conductive terminals 62, 63 are disposed in the structural body, and the first and second conductive terminals 62, 63 The first and second guiding terminals 62, 63 have a predetermined spacing, and one ends of the first and second guiding terminals 62, 63 extend into the main structure of the structure. In the body, the other end is exposed on the bottom surface of the structure body, and can be electrically connected to the applied circuit respectively. The guiding element 61 can be normally in contact with the circuit to be connected at the same time, or the normal state and the desired structure. When the connected circuit is in contact with the external force, it is used to make contact with the circuit to be connected, or to change the state of contact with the circuit to be connected, so that the circuit is disconnected. Turn on, or turn on/off the control effect of the circuit segment that was originally turned on.

It is known that an electrical switch that can be used to generate an on/off control effect can maintain the state of the switching element in a switched state by a switching action according to functions and uses; or keep the guiding element maintained by a single pressing action. The state at the time of pressing; or the continuous pressing action, the guide member is kept in a state of being pressed.

In principle, the electrical switch that constitutes the conduction of the circuit through the pressing action is provided with a pressing member for driving the guiding member to be displaced within a predetermined stroke, and an elastic reset member is disposed inside the structural body when used. After the force applied to the pressing member disappears, the elastic returning member pushes the pressing member toward the other end of the pressing stroke, so that the pressing member is held at the unstressed stroke, and the pressing force is applied to the user to cause the pressing member to actuate the guiding member. During the displacement of the connecting member toward the predetermined stroke, the elastic returning member can be simultaneously pressed, and a better operating feel can be obtained under the reaction force of the elastic force.

However, similar to the conventional push-type electrical switch, the plurality of guide members are designed to be in contact with or disconnected from the circuit, and are designed at the end of the pressing stroke of the pressing member, that is, when the user applies the pressing force to cause the pressing member to drive the guiding member. After reaching the predetermined stroke, the pressing member can not continue to move in the pressing direction under the restriction of the structural body. At this time, if the slightest care is taken, the originally turned-on circuit may be disconnected due to a slight looseness ( Or let the originally disconnected circuit turn on, and often cause the device to malfunction.

In particular, since the pressing member does not have a space that can be further displaced in the pressing direction, the user cannot further contact the guiding member after the connecting member contacts the circuit. Additional compression forces are applied, and often due to oxidation of the surface of the junction or circuit, the electrical connection is not possible.

In addition, if the connecting member is in contact with the circuit and the pressing member cannot be displaced in the pressing direction, the connecting member can be brought into closer contact with the circuit by increasing the pressing force, but it is more likely to be slightly different. The loose hand allows the originally turned-on circuit to be disconnected (or the originally disconnected circuit is turned on), which often causes the device to malfunction, and because there is no buffering effect, not only will the finger feel uncomfortable or even fatigued. .

In view of this, the present invention provides a stroke that can be continuously pressed and continuously maintained while the circuit is connected by pressing, so that the circuit connection effect is more stable and reliable, and the pressing can provide better operation feeling.
