Abstract

The utility model relates to a multiple lighting switch, which comprises a switch seat, three fixed contacts and a bipolar and convertible movable contact. When the movable contact is converted, the movable contact and the two fixed contacts are respectively in a close state. The utility model can be used for controlling the switching of a lamp on more than three different positions, can satisfy practical requirements of some occasions of residences, hotels and office buildings and can be conveniently used.

Description

Multi-joint lighting switch

The utility model belongs to appliance switch.

Existing lighting switch is generally simply connected or ganged switch, be opening or closing of an available switch or two switch lamps of control, but can not be with (comprising three more than three, down together) switch is controlled opening or closing of same lamp, when some occasion (as dwelling house, hotel, office building) need be controlled opening or closing of same lamp in positions different more than three, existing lighting switch just was difficult to accomplish.

The purpose of this utility model provides a kind ofly can both control the multi-joint lighting switch that a lamp opens or closes at three above diverse locations, to satisfy practical needs.

Multi-joint lighting switch provided by the utility model comprises switch base (5), fixed contact (1), (2), (3) and moving contact (4), fixed contact (1) and (3) are communicated with, moving contact (4) is bipolar convertible contacts, and during conversion and fixed contact (1), (2) or (2), (3) are in closure state respectively.

Below in conjunction with accompanying drawing 1 structure of the present utility model and the course of work thereof are described.

Fig. 1 is the electrical schematic diagram of schematic diagram of the present utility model and place in circuit.Control opening or closing of a lamp simultaneously with three multi-joint lighting switches (HK) among the figure, if increase this switch in the circuit, its operation principle is identical.1,2,3 is fixed contact among the figure, and 4 is bipolar convertible moving contact, and 5 is switch base, and 6 is illuminating lamp, and 7 is power supply.

When bipolar convertible moving contact of the present utility model (4) is in the closed position of fixed contact (1), (2) (as shown in Figure 1), circuit is connected, and lamp is bright; The moving contact of any one switch (4) is transformed into fixed contact (2), when (3) are closed as inciting somebody to action wherein, and circuit promptly is cut off, and lamp goes out; As changing the wherein position of the moving contact of any one switch again, circuit will be switched on again, and lamp is bright again, so just can use the utility model opening or closing of a lamp of control arbitrarily three above positions, use very convenient.

Claims

1, a kind of multi-joint lighting switch, comprise switch base (5), fixed contact (1), (2), (3) and moving contact (4), it is characterized in that fixed contact (1) and (3) are communicated with, moving contact (4) is bipolar convertible contacts, and during conversion and fixed contact (1), (2) or (2), (3) are in closure state respectively.
