Abstract

The utility model relates to a three-purpose lighting switch with the functions of safety, light regulation and the control of switching circuits. The utility model has two types which are a flat switch and a pull wire switch. The lower end of a turning handle of the flat switch is provided with an elastic knife switch. When moved, the three-purpose lighting switch contacts static contacts at both sides in order to obtain the aim of switching on the circuits. The rotational part of the pull wire switch is the same with an original switch. The different part of the pull wire switch is that a shaft of the pull switch is fixed with a ratchet wheel and vertically inserted in a round hole of a base; when the pull switch is pulled, the ratchet wheel rotates, the circuits are switched on and off at times, and the switching state of the circuits is displayed via a needle pointer on the shaft.

Description

Three-purpose lighting switch

A kind of three use lighting switch, belong to the control device in the daily household electrical appliance.

Lighting switch at present commonly used mostly is the old product of having finalized the design, function singleness, break-make that generally can only control circuit.

The purpose of this utility model is to design a kind of novel appliance switch, and its function is increased, and has insurance, light modulation, controlled function, and simple installation.

The utility model comprises insurance part, rectifier diode part.Described switch comprises turning handle (1), copper sheet (2), spring (3), static contact (4), diode (5) and cartridge fuse (6).Described switch also can comprise ratchet (1), ratchet (2), copper sheet (3), diode (4), pointer (5), backguy (6), copper sheathing (7), inserted sheet (8) and fuse (9).Described switch has a transparency window lid, also can have a complete transparent lid.

Further introduce the utility model below in conjunction with accompanying drawing with embodiment.

Fig. 1 is first embodiment of the present utility model.Wherein Fig. 1 (a) is the cutaway view of this embodiment, and Fig. 1 (b) is the front view of this embodiment.

Fig. 2 is second embodiment of the present utility model.Wherein Fig. 2 (a) is a front view.Fig. 2 (b) is a porcelain pad front elevation.Fig. 2 (c) is a porcelain pad side view.First embodiment of Fig. 1 is flat switch, and second embodiment of Fig. 2 is pulling switch.

Flat switch as shown in Figure 1.There is a rotating bakelite handle in switch central authorities, and its lower end is that two copper sheets clip a spring, is equivalent to a plug-in strip, by the elastic force of spring, follow two static contact contacts on the side.Wherein a static contact edge joint a diode.When moving handle, these two copper sheets are through the different positions of static contact, electric current in the circuit is grown out of nothing, from weak to strong, thereby regulate the light power.Insurance is installed in the latter half of of switch, and the cartridge fuse of available finished product also can be used fuse.

Pulling switch as shown in Figure 2.Its rotating part is identical with original pulling switch.Difference is major axis of ratchet center fixation, and vertically insert in the hole, garden of base the major axis lower end.During the pulling ratchet, it rotates along being parallel to the base direction, makes circuit off and on.The major axis upper end root pointer of ining succession, it follows ratchet to rotate together, has shown connecting and disconnecting of the circuit.And use the diode light modulation.Fuse is fixed on the porcelain pad on switch top.

This three use switch, and they have following advantage than original switch: 1, keep the size of original switch, fuse is put into opened section inside, do not need outside installation insurance. Make its compact conformation, reduced equipment and installation procedure. 2, set up the light modulation part, make people to light and electricity consumption the choice be arranged. 3, three usefulness pullswitches have a rotating pointer, are used for the display circuit break-make, turn off the light when reminding people to have a power failure. This is that original pullswitch does not have. 4 and add a transparent lid, can see outside whether the inside fuse fuses, and must open the lid than original safety box and just can see, more convenient.

Claims

1, a kind of three use lighting switch, it is characterized in that: described lighting switch comprises insurance part, rectifier diode part, control section.

2, lighting switch according to claim 1 is characterized in that: described switch comprises turning handle (1), copper sheet (2), spring (3), static contact (4), diode (5) and cartridge fuse (6).

3, lighting switch according to claim 1 is characterized in that: described switch comprises: ratchet (1), ratchet (2), copper sheet (3), diode (4), pointer (5), backguy (6), copper sheathing (7), inserted sheet (8) and fuse (9).
