摘要： The present invention is directed to an on/off switch for a flashlight having a reflector secured against axial motion. The reflector has a central opening. The flashlight includes a bulb with a base having an outer cylindrical electrical terminal. The bulb extends through the central opening of the reflector. The switch includes a bulb holder, with the bulb secured in and moving with the bulb holder. The switch also includes an electrical contact disposed in the flashlight so as to be adjacent and biased away from the cylindrical electrical terminal of the bulb. The switch also includes a ring rotatably disposed in the flashlight. The ring is mechanically linked to the bulb holder and includes an element disposed adjacent the electrical contact. Rotation of the ring causes the bulb holder and thus the bulb to move axially relative to the reflector due to the mechanical link and simultaneously causes the element to force the electrical contact against the bias and into contact with the cylindrical electrical terminal of the bulb.
摘要翻译：本发明涉及一种用于具有防止轴向运动的反射器的手电筒的开/关开关。反射器具有中心开口。手电筒包括具有外圆柱形电气端子的底座的灯泡。灯泡延伸穿过反射器的中心开口。开关包括灯泡保持器，灯泡固定在灯泡座中并与灯泡座一起移动。开关还包括设置在手电筒中的电触头，以便与灯泡的圆柱形电端子相邻并偏压。开关还包括可旋转地设置在手电筒中的环。环与灯泡保持器机械连接，并且包括邻近电接触设置的元件。环的旋转导致灯泡保持器并因此灯泡由于机械连接而相对于反射器轴向移动，并且同时使元件强制电接触抵抗偏压并与灯泡的圆柱形电端子接触。
