Wall coordinates, and lower end coordinates with installing sleeve 5, it is achieved seals, plays waterproof moisture-proof effect,
Wiring board 8 and electronic component thereon to lower section play a protective role.
Operation principle of the present utility model is: when original state, saturating as shift knob
Bright light guide key 2 is positioned at high point position, and live metal contact chip 3 is also at high point position,
Contactless state, i.e. open-circuit condition is kept with the top of the first metal pin 73；When by next
After secondary transparent light guide button 2, on the one hand, live metal contact chip 3 to decline therewith, with
A pair first metal pin 73 on bottom are conflicted, and with under the elastic force effect of spring 4
One metal pin 73 keeps contact closely, so that circuit turn-on；On the other hand, transparent lead
The boss 23 of light button 2 lower half moves down the most therewith so that crochet hook guide groove thereon 230 with
There is relative motion in crochet hook 6, now unclamps transparent light guide button 2, transparent light guide button 2
Under the elastic force active force of the flexible rubber ring 22 of spring 4 and PVC material, upwards return is certain
Distance, and crochet hook 6 upper end moves in the groove of crozier 24 along crochet hook guide groove 230,
Formation self-locking hook connects, and owing to the hook of crochet hook 6 with crozier 24 is connected, makes transparent
Light guide key 2 will not completely on retract position, position forms lock-out state, and switch is held on；
When again pressing transparent light guide button 2 one times, crochet hook 6 upper end is along crochet hook guide groove
230 another sides run, and after unclamping transparent light guide button 2, crochet hook 6 will be disengaged from crozier 24,
Transparent light guide button 2 loses restraining forces, in spring 4 and the effect of the elastic force of flexible rubber ring 22
The most complete return, and then make live metal contact chip 3 and first metal pin of its lower end
73 tops separate, and make circuit disconnect, so realize the switch of circuit.
And wiring board 8 and LED thereon 81, resistance 82 are by the second metal pin 83
Access other circuit, make LED luminous, the light the sent transparent light guide by top
Button 2 outwards spreads out of, so that the middle part transparent light guide button 2 of metal switch is luminous, real
Present condition indicative function and aesthetic.
In sum, this utility model is by connecting LED on the wiring board 8 of metal switch
Lamp and built-in resistor, and use transparent light guide part to replace as the parts receiving touching, with
Time switch main body be also transparent light conductive material so that during work, LED is luminous, it is achieved instruction
Effect, it is not necessary to other outside display lamps so that the application of switch is the easiest, accordingly
Equipment design also simplifies, additionally, the self-locking mechanism design of this utility model self-locking metal switch
Exquisiteness, utilizes switch side spaces, it is not necessary to additionally take up room, the most also make switch
Entire length significantly shortens, and it is the most shorter that total length can be as short as 24mm, is more suitable for compact
Space uses, and makes equipment be more easily implemented miniaturization.
