Problems solved by technology

[0006] The above methods, and the rotation angle identifier printed on the button is printed according to the locked position, but when the self-resetting knob is used, the rotation angle and the identifier will be misplaced, which will bring some misunderstandings to customers. In addition, due to the sacrifice The rotation angle is changed, and the self-resetting effect is not ideal, etc.

Embodiment 1

[0039] As shown in the figure, the present invention provides an embodiment 1, which discloses a rotary switch, which includes:

[0040] A casing 1 is provided with an arc-shaped chute 11 around the casing, and two sections of arc-shaped chute are arranged on the inner wall of the casing.

[0041] The operating mechanism 2, which is a knob, is rotatably arranged on the housing, and has at least one slider 22, which is placed in the arc-shaped chute and forms a sliding fit with it. The housing defines the rotation angle of the operating mechanism, and the slider is designed so that the movement of the slider from the first position to the second position in the arc-shaped chute drives the operating mechanism to rotate a certain angle, that is, its first position It means that the knob is at 0 degrees, and the second position means that the knob is in the working state. At the same time, the light-transmitting material is selected for the material of the knob, which can directly...

Embodiment 2

[0053] The present invention also provides an embodiment 2, which discloses a rotary switch, which includes:

[0054] A casing, arc-shaped chute is arranged on the periphery of the casing, and two sections of arc-shaped chute are arranged on the inner wall of the casing.

[0055] An operating mechanism, the operating mechanism is a knob, which is rotatably arranged on the housing and has at least one slider, which is placed in the arc-shaped chute and forms a sliding fit with it, and is defined by the housing The rotation angle of the operating mechanism, and the design of the slider makes the movement of the slider from the first position to the second position or from the first position to the third position in the arc-shaped chute drive the operating mechanism to rotate an angle , that is, the first position indicates that the knob is at 0 degrees, and the second and third positions are respectively at the angles set by the left and right rotations of the first position. T...

Abstract

The invention provides a rotary switch comprising a housing, an operating mechanism, a transmission mechanism linked and matched with the operating mechanism, push rods built in the housing in a non-rotary manner and capable of pushing an elastic element to move, a front curve surface and a rear curve surface, and a control curve surface formed between the front and rear curve surfaces and matchedwith a transmission member; an angle, corresponding to a control curve surface path, of the front curve surface equals to a rotary angle of the operating mechanism; an angle, corresponding to a control curve surface path, of the rear curve surface is greater than the rotary angle of the operating mechanism; the transmission mechanism and the push rod are matched; the corresponding angle from thefront curve surface of the push rod to the control curve surface is smaller than that from the rear curve surface to the control curve surface; push rods are arranged in a mirroring mode, thus switching locking and reset motions; the rotary angle of the operating mechanism is consistent with the angle from the front curve surface to the control curve surface, thus realizing reset and locking states under the same rotary angle.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a rotary switch. Background technique [0002] The rotary switch is to push the transmission mechanism by rotating the handle, so that the dynamic and static contacts are connected or disconnected to realize the circuit conversion. Knobs are divided into two-position knobs and three-position knobs according to their positions, including two-position self-locking, two-position self-resetting, three-position self-locking, three-position self-resetting, three-position left self-locking and right self-resetting, and three-position left self-resetting and right Self-locking. According to whether the product is illuminated or not, it can be divided into illuminated knobs and non-illuminated knobs. [0003] In order to realize switching between reset and lock, the self-reset and lock of the knob is mostly achieved by installing a stopper on the basis of the lock knob t...
