For example, the angle sensor marks the angle of the rotating member 142 as an initial angle when the rotating member 142 is in the second position with respect to the second electrode 130, and the rotating member 142 is in the first position with respect to the second electrode 130 when the rotating member 142 rotates 30 °, 60 °, 90 °, or 180 °. Those skilled in the art may be designed according to the actual situation and specific requirements, and the embodiment is not limited thereto.

More specifically, regarding the model of the angle sensor, those skilled in the art can design the angle sensor according to the actual situation and specific requirements, and the embodiment is not limited in particular.

Still further, in another embodiment, the relay 10 further includes a proximity switch (not shown) disposed on the second electrode 130 at a position tangential to the rotating member 142 and electrically connected to the driving member 141. The proximity switch is used to detect the position of the contact portion 1430, and when the proximity switch detects the contact portion 1430 when the contact portion 1430 of the outer periphery of the rotary member 142 is located at a position tangential to the second electrode 130, the proximity switch controls the driving member 141 to stop driving so that the first electrode 120 and the second electrode 130 remain on.

Specifically, regarding the type of the proximity switch, those skilled in the art may design the proximity switch according to actual situations and specific requirements, and this embodiment is not particularly limited.

In summary, an embodiment of the present utility model discloses a relay 10, in which a rotating motor 1410 drives a worm 1440 to rotate, and a worm wheel 1420 is connected to rotate around a connecting shaft, when the rotating motor 1410 drives the worm 1440 to rotate, such that the worm wheel 1420 is at a first position relative to a second electrode 130, a contact portion 1430 at the periphery of the worm wheel 1420 is separated from the second electrode 130. When the rotating motor 1410 rotates the worm 1440 such that the worm wheel 1420 is at the second position with respect to the second electrode 130, the contact portion 1430 of the outer circumference of the worm wheel 1420 contacts the second electrode 130, and the second electrode 130 communicates with the first electrode 120 through the contact portion 1430 and the conductive wire 1431. When the relay 10 is impacted, the rotating motor 1410 is fixed on the housing 110, so that the rotating motor 1410 does not have any displacement, and the worm 1440 and the worm wheel 1420 have good locking performance, so that the position of the contact 1430 on the worm wheel 1420 is not changed due to oscillation, and further, the on and off states of the first electrode 120 and the second electrode 130 are not affected by external vibration and impact, thereby improving the vibration resistance of the relay 10.

While the utility model has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing is a further detailed description of the utility model with reference to specific embodiments, and it is not intended to limit the practice of the utility model to those descriptions. Various changes in form and detail may be made therein by those skilled in the art, including a few simple inferences or alternatives, without departing from the spirit and scope of the present utility model.
