When the cap is pressed, the connecting post presses against the movable seat so that the pressing column presses against the button of the switch module. When the cap is rotated, the connecting post drives the movable seat to rotate and exert a force on the elastic element. A contact arm of the contact terminal electrically contacts the plurality of signal terminals by the rotation of the movable seat. When the force on the elastic member is removed, the elastic member is used to provide a restoring force for the movable seat and the cap to return their original positions.

Description

Rotary push switch

The invention relates to a switch, in particular to a rotary push switch with a push switch, which can be controlled by rotation, and can automatically return to position after rotation.

Whether it is an electronic device such as a 3C electronic product, a communication device, or an equipment, it usually has multiple functions or is used to control multiple appliances. Therefore, it is equipped with a rotary switch. By matching the display panel, the user can select by turning the switch. The item or function to be controlled.

The traditional rotary switch achieves the function control function through the rotation of the cap. After the rotation, the control function is achieved in different stages. It can be rotated clockwise or counterclockwise. However, after the cap is rotated, it must be manually reversed again to return. Positioning is quite inconvenient to use, especially the process of reverse turning back requires time and attention to determine that the cap has returned to positioning. In addition, after the cap is rotated to the required option, the option or function control must be completed by pressing an additional configured push switch. The setting of the push switch not only increases production costs, but also takes up limited configuration space, which is not conducive to electronic products. Layout of other internal components. Therefore, although the industry has further improved the rotary switch, it is combined with the push switch to form a rotary push switch. However, the pressing structure of the traditional knob switch is located in the middle of the overall switch, and the cap for rotation is put around the pressing structure. Therefore, an exposed gap is formed between the inner ring wall surface of the cap and the pressing part, which is easy to make the outside The entry of water vapor affects the waterproof effect of the switch, the service life of the switch, and even damages the switch.

Application-side products, in which the first gasket 23 supports the cap 2 can ensure that the cap 2 does not produce a horizontal displacement when it is pressed and displaced, and once the cap 2 is pressed and the force disappears, the first gasket 23 is generated by the pressure. It changes back to the original state, so that the cap 2 returns to its original position before being pressed.

Except that the rotary push switch 1 of the present invention can be a push control, the cap 2 can also be rotated clockwise or counterclockwise, and the movable seat 6 is rotated through the connecting column 21, and when rotated clockwise, the second elasticity of the elastic element 7 The arm 72 is pressed by the second limit groove 622 and moves along the gap 620 toward the first limit groove 621, while the first elastic arm 71 resists within the first limit groove 621 and is close to the second limit The limiting block 65 of the groove 622 is synchronously displaced until it abuts against the stopper 222, thereby limiting the rotation stroke of the movable seat 6. Similarly, if the cap 2 is rotated in the counterclockwise direction, the limit block 64 near the first limit slot 621 will be displaced until it abuts against the stop 221. The braking of the blocks 221 and 222 can prevent the movable seat 6 from being excessively rotated and causing damage to the elastic element 7. In this preferred implementation, the stop block 64 and the stop block 221 or the stop block 65 and the stop block 222 form a 30-degree angle with respect to the axis of the movable seat 6, that is, the movable seat 6 can be clockwise or counterclockwise. Turn 30 degrees in the clockwise direction.

In summary, the rotary push switch 1 of the present invention utilizes the pressing or turning of the cap 2 to synchronously drive the movable seat 6 to move down or rotate, so as to control or execute the function of the application-side product. The traditional single switch can only provide pressing Or the rotation is inconvenient, and the cap 2 can be automatically rotated and reset after the rotation, and there is no need to manually turn it back to improve convenience; furthermore, the cap 2 covers all internal components of the switch to achieve shielding protection and waterproof effect, and the first gasket The setting of 23 and the second gasket 32 greatly improves the waterproof effect, which effectively solves the shortcoming of the traditional switch that is prone to moisture.

The above detailed description is only a description of a preferred feasible embodiment of the present invention, but this embodiment is not intended to limit the scope of patent application of the present invention, and any other equivalent changes and modifications made without departing from the spirit of the technology disclosed by the present invention Changes should be included in the scope of patents covered by the present invention.
