    摘要： Proximity switches include a hermetically sealed unit that can be used in harsh environments and under significant pressures, such as underwater and in nuclear power facilities, without having any parts that would require replacement or periodic maintenance. The proximity switches are preferably switches actuated by physical movement of a contact in response to changing magnetic forces. The switches are preferably disposed in a body tube optionally including a hermetic seal assembly to seal an open end of the body tube and/or a ferrule that prevents electrical wires attached to the switch inside the body tube from being pulled away from the switch. Further, the switches preferably maintain a contact pressure between electrical contacts sufficient to withstand acceleration seismic testing of 10 g with no contact discontinuity.

    摘要翻译： 接近开关包括一个密封单元，可在恶劣环境和重大压力下使用，如水下和核电设施，而无需任何需要更换或定期维护的部件。 接近开关优选地是响应于变化的磁力而由触点的物理移动而致动的开关。 开关优选地设置在主体管中，任选地包括气密密封组件以密封体管的开口端和/或套圈，其防止附接到体管内的开关的电线从开关拉开。 此外，开关优选地保持电触头之间的接触压力足以承受10g的加速度地震测试，而没有接触不连续。

    摘要： A switch adapter can include a base having one or more openings, a support coupled to the base, and one or more retainers for coupling a switch to the adapter. The support can have one or more openings between its interior and exterior. The retainer can be adapted to couple to at least one of the base, the support, and a combination thereof. The switch adapter can include one or more switches, such as a replacement switch, and can be adapted for replacing a limit switch with a proximity switch. A proximity switch can be coupled to a switch adapter in one or more positions, and a switch adapter can be adapted to couple with a plurality of different switch mounts. A switch adapter can include a mass compensator for adjusting its center of gravity.
