Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 4, an embodiment of the present invention provides a switch assembly, which includes a base 100, a housing 400 covering the base 100, a PCB 200 laid on the base 100, the base 100 connected to the PCB 200 through a slider 300, a flow guiding structure 420 formed by an inward concave of the top of the housing 400, at least one water outlet hole 430 formed in a side of the housing 400 and connected to the flow guiding structure 420, and the bottom of the flow guiding structure 420 being inclined along a direction of the water outlet hole 430.

The utility model provides a switch is provided with water conservancy diversion structure 420 at the top of casing 400, when the operator spills water on the switch carelessly, rivers can be through the water conservancy diversion structure 420 in the casing 400 of the preferred entering in top of casing 400, under water conservancy diversion structure 420's effect, rivers pass through apopore 430 and flow, thereby avoid contacting with PCB board 200, at whole in-process, the unable inside PCB board 200 of contact switch of rivers, and then can't cause the damage to PCB board 200, the security of switch has been improved.

In this embodiment, the water outlet holes 430 are respectively disposed on two sides of the housing 400. The water outlet hole 430 is communicated with the bottom of the flow guide structure 420.
