Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. Prior to the description, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary meanings and should be construed in accordance with the technical concept of the present invention.

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

Throughout this specification, when an element is referred to as "including" an element, it is understood that it may include other elements as well, without departing from the other elements unless specifically stated otherwise.

 FIG. 2 is a cross-sectional view illustrating a structure of a switch according to an embodiment of the present invention, and FIGS. 3 to 4 are cross-sectional views illustrating a 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 a switch, a circuit board 20 mounted on the case 10, And a switch button 30 which is mounted so as to be capable of switching operation.

 2 to 4, between the circuit board 20 and the switch button 30 described above, a circuit board cover (not shown) is formed between the circuit board 20 and the circuit board 20, 110 may be mounted.

 Specifically, as can be seen in Figs. 2 to 4, the switch butt 30 may be a structure that implements a switching operation along the button holder. At this time, the switch button 30 is vertically reciprocated in a direction perpendicular to the circuit board 20 to realize a switching operation.

 In this case, a minute gap may be formed between the switch button 30 and another switch button 30. [ The foreign matter can penetrate into the switch through these fine gaps. However, as shown in FIG. 2, the switch 100 according to the present embodiment is configured such that the foreign matter infiltrated into the switch is blocked by the circuit board cover 110 to prevent the foreign matter from penetrating into the circuit board 20 .

 2, the circuit board cover 110 according to the present embodiment may be configured to include a receiving portion 111 that communicates with a gap formed at both ends of the switch button 30. In this case, as shown in FIG.

 In this case, the foreign matter penetrating into the inside of the switch from the gap between the switch button 30 and another switch button 30 can be accommodated by the accommodating portion 111. The foreign matter penetrating into the switch from the gap formed at both ends of the switch button 30 can also be accommodated by the accommodating portion 111. As a result, foreign matter infiltrated into the switch can be blocked by the circuit board cover 110 So that foreign substances can be prevented from penetrating into the circuit board 20. [

 As shown in FIG. 2, an auxiliary storage part 112, which is capable of storing foreign substances discharged from the storage part 111 and falling downward, may further be mounted on the lower part of the storage part 111.

 In this case, it is possible to more stably prevent penetration of the liquid or foreign matter penetrated into the circuit board and the penetration into the circuit board

 In some cases, a discharge port 113 may be formed in the lower portion of the storage unit 111 to discharge the foreign substances stored in the storage unit 111 to the outside.

 In this case, it is possible to prevent accumulation of foreign matter inside the switch, and consequently to extend the service life of the switch.

 Meanwhile, the above-mentioned storage portion 111 may be mounted inside the button holder, as shown in Fig.

 In this case, foreign substance penetration due to the up-and-down movement of the switch button 30 can be blocked more stably.

 In some cases, lubricating oil or a sealing material may be applied to the inside of the housing part 111 to further improve the effect of blocking the foreign matter.

 Further, 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.

 4, the circuit board cover 110 may be formed so as to surround the circuit board 20 so that the foreign matter penetrated from the outside can not penetrate into the circuit board 20. As shown in FIG.

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

 The present invention can also provide a temperature control device for a vehicle including the above-mentioned switch (100). According to the temperature control device for a vehicle of the present invention, damage to an internal structure or internal electronic components It is possible to provide a more stable and reliable vehicle temperature control device.
