2 is a cross-sectional view showing the structure of a switch according to an embodiment of the present invention.
3 is a cross-sectional view showing the structure of a switch according to another embodiment of the present invention.
4 is a cross-sectional view showing the structure of a switch according to another embodiment of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, the terms or words used in the present specification and claims should not be construed as being limited to ordinary or dictionary meanings, but should be construed as meanings and concepts consistent with the technical spirit of the present invention.

Throughout this specification, when a member is located "on" another member, this includes not only when one member is in contact with another member but also when another member exists between the two members.

Throughout this specification, when a part is said to "include" a certain component, it means that it can further include other components, without excluding other components unless otherwise stated.

 2 is a cross-sectional view showing the structure of a switch according to an embodiment of the present invention, Figures 3 to 4 is a cross-sectional view showing the structure of a switch according to another embodiment of the present invention.

 Referring to these drawings, the switch 100 according to the present embodiment includes a case 10 supporting a lower portion of the switch, a circuit board PCB 20 mounted on the case 10, and an upper portion of the circuit board 20. The switch button 30 may be configured to be mounted to enable a switching operation.

 At this time, as shown in Figures 2 to 4, between the circuit board 20 and the switch button 30 mentioned above, the circuit board cover (so as not to penetrate the foreign matter penetrated into the circuit board 20) 110 may be mounted.

 Specifically, as can be seen in Figures 2 to 4, the switch butter 30 may be a structure for implementing a switching operation along the button holder. In this case, the switch button 30 may implement a switching operation by vertically reciprocating in a direction perpendicular to the circuit board 20.

 In this case, a fine gap may be formed between the switch button 30 and another switch button 30. Foreign matter can penetrate into the switch through these tiny gaps. However, as shown in FIG. 2, the switch 100 according to the present embodiment blocks the foreign matter penetrated into the switch with the circuit board cover 110 to prevent foreign matter from penetrating into the circuit board 20. Can be.

 In some cases, as shown in FIG. 2, the circuit board cover 110 according to the present exemplary embodiment may have a configuration including an accommodating part 111 communicating with gaps formed at both ends of the switch button 30.

 In this case, foreign matter penetrating into the switch from the gap between the switch button 30 and another switch button 30 can be accommodated by the housing 111. In addition, foreign matter penetrating into the switch from the gap formed at both ends of the switch button 30 can also be accommodated by the housing 111, and as a result, the foreign matter penetrated into the switch is blocked by the circuit board cover 110. Thus, foreign matters can be prevented from penetrating into the circuit board 20.

 In addition, as shown in FIG. 2, an auxiliary accommodating part 112 may be further disposed below the accommodating part 111 to accommodate the foreign matter discharged from the accommodating part 111 and falling downward.

 In this case, it is possible to more stably prevent the infiltration into the circuit board by storing the liquid or foreign matter penetrated inside.

 In some cases, the lower portion of the accommodating portion 111, the discharge port 113 for discharging the foreign matter stored in the accommodating portion 111 to the outside may be further formed.

 In this case, foreign matter can be prevented from accumulating inside the switch, and consequently, the life of the switch can be extended.

 Meanwhile, the aforementioned accommodating part 111 may be mounted inside the button holder, as shown in FIG. 3.

 In this case, it is possible to more stably block foreign matter infiltration due to the vertical movement of the switch button 30.

 In some cases, by applying a lubricating oil or a sealing material to the interior of the housing 111 can further improve the foreign matter blocking effect.

 In addition, a sealing member may be mounted between the circuit board cover 110 and the circuit board 20 to further improve the foreign matter blocking effect.

 In addition, as shown in FIG. 4, the circuit board cover 110 may be formed in a structure surrounding the circuit board 20 so that foreign matter penetrated from the outside does not penetrate the circuit board 20.

 In this case, a more reliable sealing effect can be achieved, and as a result, damage to the circuit board due to external foreign matter penetration can be prevented at the source.

 The present invention can also provide a vehicle temperature control apparatus including the above-mentioned switch 100, according to the vehicle temperature control apparatus of the present invention, the damage to the internal structure or internal electronic components by external foreign matter penetration. Since it is provided with the switch which can prevent, it can provide a more stable and reliable vehicle temperature control apparatus.
