Abstract

The utility model discloses an improved switch for pendant lamps, in particular to a switch for the pendant lamps which can control one or more bulbs. The utility model is suitable to the adjusting control of illumination lamps, the pendant lamps and lamp groups in meeting rooms, restaurants and homes. Compared with exiting illumination lamp switches, the switch for the pendant lamps has the functions of which the utility model can control the opening of one, two, three or more than three lamps on the pendant lamps making use of a switch, can change wire connection processes as required for the crossed opening or shutting of the illumination lamp on the pendant lamps, reduces the amount of the switch and saves power.

Description

Rotory switch for pendant lamp

The utility model relates to a kind of improved pendent lamp control switch, the particularly a kind of pear switch that can control 1 to a plurality of illuminating lamps.Be applicable to meeting room, dining room, hotel, home-use illuminating lamp, pendent lamp, lamp group's adjusting control.

The prior mechanical lighting lamp control switch is made of the loop line binding post of patterns such as single firewire binding post and button, spring-plate type, stay-supported, contact, and its function all is that a switch can only be controlled a light fixture, and non-opening promptly closed; If Assembled lamp group or pendent lamp are arranged, for avoiding unnecessary whole unlatchings, then need to arrange the control switch more than 2 or 2, Kong Zhi result is that control switch increases like this, reasonably illuminating effect often takes place inadequately during use, or waste unnecessary electric power.

Task of the present utility model provides a kind of revolving pendent lamp control switch, can control a plurality of bulbs or fluorescent tube on the light fixture by a switch, make it turn on one, two, the lamp more than three and three, can make lighting bulb open, close equally according to the connection of each contact lead on switch with staggered form.

The utility model is to come work in the following manner.

The utility model is that a switch closes, and has panel and end cover cap to constitute.A garden shape insulation board is installed at the back side of panel, according to the number of design needs decision may command lamp holder, leaves the number (using) of conductive contact on the limit, garden of insulation board, add 1 conductive contact and use as the conduction live wire as the conduction loop line.On the heart position, garden of insulation board Control Shaft is housed, axle head on panel can be equipped with a banana-shaped conductive metal sheet by a control knob on the Control Shaft below the panel, driven rotary axle when the Spin Control button, the banana-shaped conductive metal sheet that is fixed on the axle is also rotated, and touch mutually with first conductive contact, then the banana-shaped conductive metal sheet becomes the live wire end, rotation forward again, then the banana-shaped conductive metal sheet contacts other conductive contacts, and the bulb that then links is opened one by one, until whole unlatchings; The opposite spin rotating shaft, then bulb is closed one by one, reaches to utilize a switch to control the purpose of a plurality of bulbs.According to the change of lead connection, the position of can conversion opening bulb.

Accompanying drawing is an embodiment:

Fig. 1 is the pear switch schematic diagram;

Fig. 2 is the switchboard schematic diagram of pear switch, and Fig. 2-1 is positive, and Fig. 2-2 is the back side.

The rotary pendent lamp control switch of the utility model indication is by knob (1), panel (2), end cover cap (3) constitutes whole switch, on the set bolt of panel (2), plate is fixed on the back side of panel (2) by the fixing hole (13) on the garden shape insulation board (4), a rotating shaft (5) is adorned in the heart position, garden of its garden shape insulation board, it is by an end of panel, knob (1) can be fixed, on the rotating shaft between panel and garden shape insulation board, load onto insulating guide rod (6), go up fixedly a slice banana-shaped metallic conduction sheet (7) at insulating guide rod (6), this banana-shaped metallic conduction sheet (7) can be by rotation axis (5), guide rod (6) and make it the rotation, touch a plurality of conductive contacts (8) set on garden shape insulation board (4) the Wai Yuan limit when rotated.When contacting first contact, banana-shaped metallic conduction sheet connects live wire (first conductive contact has connected live wire), when rotation touches second, the 3rd forward, cause is since second all conductive contact that conductive contact is set, all tie mutually with the loop line of lead, touch second and third conductive contact (8) so work as banana-shaped conducting strip (7), then circuit is connected, and the bulb of binding is then opened.Rotating shaft (5) sees through end dress a slice metal spring sheet (9) of garden shape insulation board (4), spring leaf is pushed down a sounding positioning ball (10), steel ball can determine that the position of the switch can not drift about, because at the position of garden shape insulation board (4) near the garden axle, according to conductive connector (8) position of the length of spring leaf (9) and setting and have steel ball seat hole (11) on definite position, with nut rotating shaft is fixed at last.Be rotated on the fixing position sounding location for making, be no more than rotating range, a barrier post (12) can be set, back cover upper base cover cap (3).

The mark with the conductive contact position consistency should be carved with in the front of panel (2), with the turned position of indication knob, determines which bulb opens, and which is not opened.Should be furnished with for connecting the wiring point of bulb lead, for use on all binding posts.

Claims

1, the pear switch of a kind of rotary contact conduction control bulb switching, it is characterized in that on the edge of garden shape insulation board (4), arranging a plurality of conductive contacts (8), heart position, garden is provided with a rotating shaft, the banana-shaped conductive metal sheet (7) that insulating guide rod (6) is housed on the axle and links with it, retainer spring sheet metal (9) with it, at the back side of garden shape insulation board (4) sounding positioning ball (10) is housed, whole garden shape insulation board can be covered by end cover cap (3), and be contained in the back side of panel (2), panel front has graduation mark, and a knob (1) is housed.

2, according to the conductive contact (8) of claim 1, it is characterized in that the lamp number that can control as required this contact determines, generally can be provided with 2～5, also can be provided with more than 5.

3, according to the banana-shaped sheet metal (7) of claim 1, it is characterized in that its length can prolong with the increase of conductive contact (8), its width is a standard contacting with conductive contact.

4, according to the position that is provided with of the conductive contact (8) of claim 1 and banana-shaped conductive metal sheet (7) and steel ball seat (11), it is characterized in that all should be on the concentric garden of garden shape insulation board (4).
