Wall-mounted switch

Abstract

Disclosed is a wall-mounted switch. Tilting action of a lever (16) is transmitted to a movable contact (25) on a spindle (26) through a small support (18), a slider (17) and a connecting shaft (29) to drive the movable contact (25) to complete open and close action. A free trip device comprising a snap catch (27) and a lock catch (28) can also be arranged on the wall-mounted switch, and functions of earth leakage protection, short-circuit protection and overload protection are realized by cooperation of various trippers arranged beside the lock catch and a detection circuit. An operating mechanism is arranged on one side of a switch center, so that enough wiring space and radiating space of a load end can be reserved for arrangement of essential devices for making and breaking large load on the condition of small-size standard household switch, or enough space can be reserved for arrangement of test buttons on a panel, a test circuit inside, indicating lights and the like when a socket is used as an output device, and therefore, the wall-mounted switch is light, attractive and convenient.

Description

technical field [0001] The invention relates to a wall switch used in buildings in the field of electrical appliances, in particular to a wall switch with protection functions such as overload, short circuit, and leakage for household large loads. Background technique [0002] Switches used in buildings, such as wall switches, are largely of the household type. [0003] The very popular wall switch on the market is a rocker switch, which is beautiful and elegant, and is very in line with the aesthetic concept of modern people's home furnishing. However, the current rocker-type wall switch is only a rocker switch with two stable positions and a very simple structure. It only has the function of connecting and breaking the circuit, and can only be used in occasions with small power, and does not have free tripping. and various protection functions. There is also a switch called the handle-operated type. When the switch is closed, the handle is pulled to make it rotate at a l...

AI Technical Summary

Problems solved by technology

And this switch is because the shape is huge, and the operating handle and the overall shape are not beautiful, which does not meet the aesthetic concept of modern people's home furnishing.

In addition, the handle-operated switch is difficult to realize the seesaw operation due to structural problems, because it rotates at a large angle during operation, but the rotation angle when using the seesaw operation is only about 15 degrees.

However, the rocker switch cannot rely on continuous rocker action to obtain sufficient contact opening distance and overtravel for the contact system of the switch.

On the other hand, this kind of rocker wall switch is also difficult to realize the link-type operating mechanism due to structural problems, and it is also difficult to realize the free tripping of the mechanism. Without free tripping, various protection functions cannot be realized.
