    摘要: A sealed contact unit that attains stabilized contact switching operation and effective dimensional minimization with an arrangement wherein a switching contact section including opposing movable and stationary contacting members is housed within a sealed container together with an electrically insulating gas, a movable shaft interlocked to the movable contacting member is hermetically passed through a wall of the container to be axially shiftable with an end projected externally while the movable contacting member biased away from the stationary contacting member by a resetting spring is mounted through a contact-pressure spring to the other end of the movable shaft inside the container, the contact-pressure spring being provided to coaxially enclose the movable shaft and biasing the movable contacting member against the biasing force of the resetting spring for attaining a contact-pressure when the movable contact member shifts to engage the stationary contact member fixed inside the container, a driving section for switching ON and OFF between movable and stationary contacts of the movable and stationary contacting members is engaged to the projected end of the movable shaft for axial drive of the shaft.
