    • The present invention relates to a switch device (100) for use in hand-held power tools. The switch device (100) may include at least one chamber (102) whose interior serves as an accommodation space. The chamber (102) may partially encase an operational member (104) for actuating the hand-held power tool through the switch device (100). Further, the switch device (100) is provided with multiple holes (202) on side walls (204) of the chamber (102) to create a passageway for external particulate materials. Also, a bottom surface (205) of the chamber (102) may be sloped to extend from an interior of the chamber (102) to each of the multiple holes (202), to enhance the discharging of the external particulate materials through the holes (202).
    • 本发明涉及一种用于手持式电动工具的开关装置(100)。 开关装置(100)可以包括至少一个腔室(102),其内部用作容纳空间。 腔室(102)可以部分地包围操作构件(104)以用于通过开关装置(100)致动手持式工具机。 此外,开关装置(100)在腔室(102)的侧壁(204)上设置有多个孔(202),以形成用于外部颗粒材料的通道。 而且,腔室(102)的底表面(205)可以倾斜以从腔室(102)的内部延伸到多个孔(202)中的每一个,以增强外部颗粒材料通过孔 (202)。
