Mercury relays offer much faster switching than mechanical contactors, and though not as fast as solid state devices, are far more economical and can be mounted in a smaller foot print. Mercury relays are hermetically sealed with high quality glass to metal seals. The stainless steel tube is totally encapsulated in high grade UL approved epoxy to prevent moisture damage and voltage breakdown through the protective coating. The coils are wound on compact nylon bobbins and molded onto the metal tube to provide minimum power loss. This allows for low coil power required to actuate the contactor. This also enables the units to handle high loads with minimum de-rating due to higher ambient temperatures. Inert gases internally prevent excessive arcing between the mercury and the electrodes which enables the unit to function for millions of cycles with very low contact resistance, and minimum deterioration of the internal parts. Available in all standard coil voltages, in single, two and three pole arrangements: Other coil voltages available upon request. In multiple pole units each tube is actuated by its own coil. This eliminates pull-in variation between contact tubes, assuring consistent switching.

水銀繼電器比機械接觸器提供更快的開關, 雖然不像固態設備那么快, 但更經濟, 可以安裝在一個較小的腳印。水銀繼電器密封, 高品質的玻璃, 以金屬密封。不銹鋼管完全封裝在高品位的 UL 認可的環氧樹脂, 以防止濕氣損害和電壓擊穿通過保護涂層。線圈纏繞在緊湊的尼龍管上, 并模壓到金屬筒上, 以提供最小的功率損耗。這允許低線圈功率驅動接觸器。這也使單位能夠處理高負荷, 因為更高的環境溫度, 最低的降級。惰性氣體內部防止汞和電極之間的過多電弧, 使得該裝置能夠在極低接觸電阻的數以百萬計的周期中運轉, 內部部件的最小劣化。可在所有標準線圈電壓, 單, 二和三極點安排: 其他線圈電壓可根據要求提供。在多桿單位每管由它自己的線圈驅動。這消除了接觸管之間的拉入變化, 保證了一致的切換。
