Description

Rotary switch with remote control switching function

Technical Field

The invention belongs to the technical field of switches, and particularly relates to a rotary switch with a remote control switching function.

Background

The words switch are to be interpreted as open and closed. It refers to an element that can open a circuit, interrupt a current, or cause it to flow to other circuits. The most common switches are electromechanical devices that are operated by a person, in which there are one or several contacts. The "closed" of a contact indicates that the contact is conductive, allowing current to flow; an "open" of the switch indicates that the contact is not conductive, creating an open circuit, and not allowing current to flow. The development history of switches has been developed from original knife switches requiring manual operation to modern intelligent switches used in various large electrical control devices, and the functions of the switches have been increased and the safety thereof has been improved, and a rotary switch is a common switch that prevents unauthorized operation of a rotary operating device by locking a rotary operator at a specific position corresponding to a specific state of the rotary operating device. With the development of the technology, especially in a photovoltaic system, a requirement for a remote switching function of a rotary switch gradually arises, for example, when a fire occurs in a photovoltaic panel, a remote control is needed to disconnect a circuit, and a commonly used means for realizing the remote switching function is to add a motor at an operating handle position of the switch, drive the rotary switch through the motor, and further realize that the rotary switch disconnects the circuit. However, the scheme of the motor not only causes the volume of the whole rotary switch to be very large, but also causes the cost to be very high, and the motor usually needs a running time of several seconds to realize switching, and needs to be supplied with power continuously and has a slow response speed, so that the motor is difficult to be popularized in a photovoltaic system.
