The use of "first," "second," and similar terms in the description and in the claims does not indicate any order, quantity, or importance, but rather is used to distinguish one element from another. Also, the use of the terms "a" or "an" and the like do not necessarily denote a limitation of quantity. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

The present invention is described in detail below by way of describing example embodiments.

As shown in fig. 1, the swing handle apparatus 1 according to the present invention may include an operating handle 10 and a housing 20. The operating handle 10 is mounted in an opening 21 (shown in fig. 2) of the housing 20. The operating handle 10 can be rotated relative to the housing 20. The operating handle 10 is provided with an indicator 11, so that when the operating handle 10 is rotated, the indicator 11 can indicate the current position. As shown in fig. 1, the indicator 11 is in a pattern, for example, a triangle, which may also be in the shape of an arrow. The housing 20 is provided with a plurality of light guiding columns 22, three light guiding columns 22 are shown in fig. 1 and 2, passing through the wall of the housing 20 radially outside the opening 21, it being understood that the number of light guiding columns 22 may correspond to the number of rotational positions of the operating handle 10, e.g. there may be 2, 4 or more light guiding columns 22. The position of the light guide 22 may correspond to a rotational position of the operating handle 10 such that when the operating handle 10 is rotated to one of a plurality of rotational positions, the indicator points to exactly a respective one of the plurality of light guides. The plurality of light guide posts 22 are preferably disposed near the periphery of the opening 21 and spaced apart at the same interval. The plurality of light guides 22 are configured to have different colors from each other, for example, in the example of three light guides 22 of fig. 1 and 2, the colors of the light guides 22 may be red, yellow, and green.

As shown in fig. 3 and 4, the swing handle apparatus 1 according to the present invention may further include a dial 30 disposed within the housing 20 so as not to be visible in fig. 1 and 2. The dial 30 is attached to the operating handle 10, for example, fixed to the operating handle 10 at a circle center (for example, a triangle of the center as shown in fig. 4 is inserted into a groove of the operating handle 10), so that the dial 30 rotates together with the operating handle 10. The dial 30 has a diameter larger than that of the operating handle 10. The dial 30 comprises only one light source 31 arranged on the dial 30 on the side facing the operating handle 10, the position of the light source 31 corresponding to the position of the indicator piece 11, in other words, the light source 31 and the indicator piece 11 are on the same radius, so that the light source 31 and the indicator piece 11 are located in the same radial direction regardless of the rotation of the operating handle 10 and the dial 30. Also, the position of the light source 31 is set radially outside the operation handle 10 so that the light emitted from the light source 31 is not blocked by the operation handle 10. As shown in fig. 4, the dial 30 may further include a circuit board 32 and a power supply 33 provided on the dial 30 on a side facing the operation handle 10 to supply power to the light source 31. Also, the power supply 33 may always supply power to the light source 31 without interruption. The light source 31 may be a light emitting device, such as an LED, more specifically an SMD LED. The light source 31 is configured to emit white light, for example.

Thus, when the operating handle 10 is rotated to direct the indicator 11 to one of the rotational positions, that is, when the indicator 11 is directed to one of the light guide posts 22 corresponding to the rotational position, the light source 31 rotates with the turntable 30 to the lower side of the light guide post 22, and the light emitted from the light source 31 is transmitted to the outside of the housing 20 through the light guide post 22, as shown in fig. 1, so that the user can see the light. It should be noted that when the light source 31 is rotated to a position under a certain light guide 22, the light source 31 and the light guide 22 are close enough and/or the light guide 22 is far enough apart, so that the light source 31 is only transmitted to the outside of the housing 20 through the light guide 22, i.e. the user can only see the light emitted from the light guide 22 and not the other light guides 22. Because the light guide 22 is colored, the white light transmitted through the light guide 22 will display the color of the light guide 22. For example, when the light guide 22 is red, yellow, and green, the light transmitted through the light guide 22 is red, yellow, and green. Different colors may be preset to correspond one-to-one to different rotational positions of the rotary handle device 1. In this way, when the user sees the color of the emitted light, the user can recognize the current position of the swing handle apparatus 1, and the state of the swing handle apparatus 1 can be visualized, which is particularly advantageous in dark conditions. Moreover, the structure for realizing the function is simple, only one light source 31 is needed, and the electric power is saved.

According to the present invention, the swing handle device 1 may be included in a circuit breaker. The circuit breaker may have a closed position, a fault position, and an open position. Correspondingly, the light guide posts 22 of the rotary handle device 1 are a red light guide post 22, a yellow light guide post 22 and a green light guide post 22. When the operating handle 10 is rotated to the on position of the circuit breaker, the light source 31 is also rotated to the on position, and the white light is led out red light through the red light guide column 22; when the operating handle 10 is rotated to the fault position of the circuit breaker, the light source 31 is also rotated to the fault position, and the white light is guided out of the yellow light through the yellow light guide column 22; and when the operating handle 10 is rotated to the opening position of the circuit breaker, the light source 31 is also rotated to the opening position, and the white light is directed to green light through the green light guide 22. Therefore, the user can clearly distinguish the current position of the circuit breaker from the difference of the colors, and the circuit breaker is convenient and safe.

The exemplary embodiments of the twist grip device 1 and the circuit breaker according to the present invention have been described in detail with reference to the preferred embodiments, however, it will be understood by those skilled in the art that various modifications and changes can be made to the above-described embodiments without departing from the concept of the present invention, and various combinations of the various technical features and structures of the present invention can be made without departing from the scope of the present invention.
