VACUUM INTERRUPTER AND DISCONNECT COMBINATION Abstract of the Disclosure A compact combination vacuum interrupter and visible break disconnect switch, in which the interrupter is electrically connected in series with the disconnect. The interrupter is manually closed, and can be tripped manually or automatically on overcurrent or undervoltage line conditions by a quick make, quick break, trip-free operating mechanism. The disconnect is manually opened or closed by a separate operating mechanism, which is mechanically inter- locked with the interrupter operating mechanism so that the disconnect cannot be opened when the interrupter is closed, or the interrupter cannot be closed when the disconnect is open. The disconnect can be padlocked in its open position. The interrupter is mounted integral with the movable contact of the disconnect on a pivotable, insulating support member of the disconnect, with the movable contact rod of the interrupter pivotably connected to the interrupter operating mechanism. When the interrupter is in its open position, the pivotal axis of the interrupter movable contact rod coincides with the pivotal axis of the disconnect insulating support member, so that, when the disconnect is opened, the interrupter is pivoted about the same axis as the disconnect movable contact while the interrupter contacts are maintained at their fully open position.
