Description

[Detailed Description of the Invention] The present invention relates to a switch with an indicator light that is used by being attached to an embedded wiring box, and is intended to provide this type of switch that is easy to assemble.

An embodiment of the present invention will be described below with reference to the drawings. In the drawings, 1 is a switch box made of an insulating material, 2 is a transformer storage chamber formed at the center bottom of the box 1, and 3 is a transformer stored in the storage chamber. Terminals 4, 5 are attached to the primary coil of the transformer, and plug blade receiving terminals 7, 7 are attached to the tips of the secondary coil lead wires 6, 6 by soldering or the like. Reference numeral 8 denotes an insulating plate having rectangular openings 9 and 10 drilled in its plate surface through which the primary coil terminals 4 and 5 of the transformer 3 are inserted. V-shaped cut grooves 11, 11 are provided in the insulating plate 8, and the insulating plate 8 is inserted into the upper surface of the transformer 3 with the primary coil terminals 4, 5 of the transformer 3 inserted into the rectangular openings 9, 10. It is placed there. 13 is a conductive plate fitted into the frame 12 of the insulating plate 8; 14 is a light emitting diode and plug blade terminal 1
5 and 15, and is installed in a storage hole drilled at the periphery of the rectangular opening of the lid body 20 into which the switch button 19 is rotatably fitted, and the plug blade terminal 1 of the light emitting diode 14
5 and 15 are the secondary line ring plug blade receiving terminals 7 of the transformer 3,
7 is plugged in and connected. Reference numeral 16 denotes a movable element whose one end is supported in V-shaped cut grooves 11, 11 formed in the frame 12 of the insulating plate 8, and whose other end is supported under pressure by a spring 18 fitted into the switch button 19. 16
is connected to the transformer 3 via the conductive plate 13 in the frame 12.
It is electrically connected to the primary side wire terminal 5 of.
21 is a bent terminal metal fitting that electrically contacts the other terminal 4 of the primary side wire ring of the transformer 3; 22 is a bent terminal fitting that faces the contact 17a of the movable element 16, which tilts elastically when the switch button 19 is operated; A terminal fitting to which the fixed contact 17b is attached, 23 and 23 are locking plate springs 26 that press the electric wires 24 and 25 to the terminal fittings 21 and 22;
is a metal fitting that crimps and fixes the box 1 and the lid 20 into one body, and when the switch button 19 is operated in the switch with the indicator light of the present invention configured as described above, the contact 17a of the movable element 16 and the terminal metal fitting 22 are connected. contacts 17b of the transformer 3, the primary side circuit of the transformer 3 is closed, and the light emitting diode 14 connected to the secondary line ring plug blade receiving terminals 7, 7 of the transformer 3 lights up, indicating that the switch circuit is closed. do.

The present invention is as described above, in which the transformer 3 is housed in the storage chamber 2 formed at the center bottom of the box 1, and the rectangular opening 9 is formed into which the primary wire terminals 4 and 5 of the transformer 3 are inserted. , 10 is placed, and the bent part of the terminal fitting 21 for connecting the electric wire is placed on one of the coil terminals 4 exposed on the surface of the insulating plate, and by operating the switch button 19. A movable element 16 having a contact 17a that tilts elastically and comes into contact with and separates from a fixed contact 17b of a terminal fitting.
One end of the conductive plate 1 is supported in a cut groove 11 formed in the frame 12 of the insulating plate 8, and the movable element 16 and the primary coil terminal 5 of the transformer 3 are fitted into the frame 12.
Since the switch is electrically connected through the switch 3, it is very easy to assemble and can be mass-produced, making it possible to provide this type of switch at a low cost.
