Description

Rotary electric switch Technical Field The utility model belongs to the technical field of electrical switches, and particularly relates to a rotary electrical switch. Background An electrical control switch is simply an electrical switch, which is a switching device for converting electrical current, most typically an electrical switch having at least a contact system, i.e. a movable contact and a fixed contact. The contact system of a conventional electrical switch is provided in a box or housing, i.e. a movable contact and a fixed contact are arranged in the box or housing, which can be mechanically separated or brought together for breaking or completing the current of the electrical circuit. The utility model patent with publication number CN220526803U discloses a rotary controlled electric switch, which comprises a shell, a first guide post, a guide sleeve, a conductor and a knob component, wherein the first guide post is arranged in the shell, a groove is formed on the peripheral wall of the first guide post, the guide sleeve is arranged outside the shell, the conductor is made of metal material, passes through the inside of the guide sleeve and is inserted in the inside of the first guide post, one end of the conductor is used for connecting electricity, the knob component is rotatably inserted in the shell, the knob component is contacted with the other end of the conductor through rotation of the knob component, the knob component is contacted with the inside of the groove at the same time when the knob component is contacted with the other end of the conductor, the knob component can not drop, the knob component is contacted with the other end of the conductor, and a contact system in the electric switch keeps electrifies the circuit. However, the existing switch lacks the buffer design and is not assisted by an elastic element, so that the impact force is large when the switch rotates in place, the operation hand feeling is hard, the groove or the support rod is easy to wear after long-term use, and limit failure is caused. Moreover, when the equipment vibrates, the knob member can axially displace due to inertia or resonance, so that contact gaps are increased, poor contact of a circuit is caused, the knob member is limited only by the support rod, a locking mechanism is lacked, the knob can be rotated accidentally due to the fact that a handle is touched by mistake, the circuit is cut off, and the equipment is not suitable for a high-frequency operation scene. The present utility model has been made in view of this.
