Embodiment
The utility model is a kind of microswitch with light-emitting component, below conjunction with figs. is illustrated technology contents of the present utility model.See also Fig. 1 to Fig. 4, Fig. 1 is to Figure 4 shows that the utility model one embodiment microswitch, wherein Figure 1 shows that the schematic appearance of this microswitch, Fig. 2, Figure 3 shows that the generalized section of front surface A-A direction, B-B direction, and Fig. 4 is the C-C directional profile schematic diagram of side.This miniature switch has a shell 1, is separated out the accommodation space 100 that an assembling space 10 and has single opening in this shell 1.Installing passes one first conductive feet 31, one second conductive feet 32 and the one group of activity switching mechanism 2 to this shell 1 in this assembling space 10, and this activity switching mechanism 2 comprises the electroconductive elastic sheet 24 that top 22 and that a keycap 21, that exposes to this shell 1 is installed in these keycap 21 belows is subjected to these top 22 ejections at least.This top 22 joins with this keycap 21, and being butted on this electroconductive elastic sheet 24 of this top 22 normalities, so this keycap 21 can be by this top 22 and this electroconductive elastic sheet 24 of interlock.This electroconductive elastic sheet 24 is subjected to this keycap 21 interlocks, and has the primary importance that connects this first conductive feet 31, second conductive feet 32, and makes this first conductive feet 31, second conductive feet 32 form the second place that opens circuit.These top 22 activities for convenience also comprise a spring 23 between this keycap 21 and this top 22, when allowing these keycap 21 actions, this top 22 can have the space of shrinking back.The opening of this accommodation space 100 is provided with a light-guiding shade 5, and is provided with a support portion 101 in this accommodation space 100, and a light-emitting component 4 is supported in these 101 tops, support portion, and this light-emitting component 4 can be light-emitting diode.In the embodiment shown in Figure 2, this support portion 101 can be a flexible member.This light-emitting component 4 further is shown among Fig. 3, Fig. 4 and Fig. 5 has, and be provided with two power supply pin 61,62 and pass this shell 1 and enter in this accommodation space 100 to the horizontally extending power connection end 41,42 in both sides.This power supply pin 61,62 respectively is provided with a bending segment 610,620, described bending segment 610,620 is butted on two power connection ends, 41,42 tops of this light-emitting component 4 respectively, and by this contact the power connection end 41,42 of this power supply pin 61,62 and this light-emitting component 4 is electrically connected.And, owing to described bending segment the 610, the 620th, being butted on the top of this power connection end 41,42, the space of having limited these power connection end 41,42 displacements makes this light-emitting component 4 be positioned in this 101 tops, support portion.And, this power supply pin the 61, the 62nd, what be used for normality connects a direct current electric power to light this light-emitting component 4, makes this this light-guiding shade 5 of light-emitting component 4 luminous irradiations, and the designer can determine the shape of this light-guiding shade 5 according to lighting demand.
See also Fig. 6, above-mentioned microswitch is less owing to volume, so can be provided with an effort handle 211 that protrudes on this keycap 21, and the user can be forced on this keycap 21 by this effort handle 211.Because above-mentioned technology utilizes described bending segment 610,620 to prop up the power connection end 41,42 of this light-emitting component 4, and light-emitting component 4 belows also have this support portion 101 supporting, so the power that upper and lower applies respectively is positioned this light-emitting component 4.And compare with existing structure, because the utility model utilizes this bending segment 610,620 assist location, therefore this shell 1 does not need to form imperceptible fixed structure (because microminiaturization of construction of switch and light-emitting component 4) when ejection formation, can promote the part yield and reduce production costs, and reduce the difficulty of assembling.
Though the utility model discloses as above with preferred embodiment, yet it is not in order to limit the utility model.Anyly have the knack of this operator, in not breaking away from spirit and scope of the present utility model, and done some change and retouching, all should be covered by in the utility model, therefore protection range of the present utility model should be looked accompanying Claim and defines and be as the criterion.
