摘要： An opening which leads inside a surface-moutable switch is sealed by a tape seal, a good seal being maintained even when heat is applied to the switch. A switch body has a top surface and an inner space in which an electrical contact is provided. A switch knob operating the electrical contact provided inside the switch is accessed through the opening. The tape seal seals the opening with an adhesive applied between the tape seal and a top surface of a switch body. A portion of the tape seal directly above the opening is drawn into the opening by a negative pressure in the opening. The surface-mountable switch is manufactured by placing the switch body applied with the tape seal in a vacuum chamber so as to evacuate air surrounding the switch body. The seal for the opening is temporarily broken by an air pressure inside the opening, and the pressure inside the opening becomes a negative pressure with respect to the atmospheric pressure. The portion of the tape seal directly above the opening is drawn into the opening. The switch body applied with the tape seal may be simply heated so that the air inside the opening is expanded. The expanded air is abruptly discharged through an air vent opening formed between the tape seal and the switch body. A negative pressure is generated in the opening to draw the tape seal into the opening, and the opening is hermetically sealed.

摘要翻译： 引导在表面开口开关内的开口由带状密封件密封，即使在对开关施加热量时也保持良好的密封。 开关体具有顶表面和内部空间，在该内部空间中设置有电触点。 操作开关内部的电气触点的开关旋钮通过开口进入。 胶带密封件用施加在带密封件和开关体的顶表面之间的粘合剂密封开口。 直接在开口上方的胶带密封件的一部分通过开口中的负压被吸入开口中。 可表面安装的开关通过将施加有带密封件的开关主体放置在真空室中以便排空开关体周围的空气来制造。 开口的密封件由开口内部的空气压力暂时断裂，并且开口内的压力相对于大气压变为负压。 直接在开口正上方的胶带密封部分被拉入开口。 施加带密封件的开关体可以简单地加热，使得开口内的空气膨胀。 膨胀的空气通过形成在带状密封件和开关体之间的排气口突然排出。 在开口中产生负压以将带密封件拉入开口，并且开口被气密密封。
