Abstract
An electrical isolator has an insulated housing with input and output conductors (1, 2) therein. A spring contact (6) is mounted within the housing for movement between open and closed positions. An insulating shroud (15) fully shields that part of the bridging contact accessible through an access opening of the housing. Manually operable pressure applying structure may be operated when the bridging contact is in the closed position to control that contact between a tightened condition applying pressure between the bridging contact and the conductors without the use of springs, and a free condition wherein the contact pressure is reduced. An interlock assembly prevents engagement and disengagement of the operating member with the pressure applying structure unless the bridging contact is located in either the closed or open position.
