    摘要： A transfer switch configured to transfer connection of each power conductor and neutral conductor of a load between two power supplies. The transfer switch includes a switch member configured to transfer each of the connections in tandem. The transfer switch disconnects each power conductor prior to disconnecting the neutral conductor of the first supply when disconnecting the load from either power supply and connects the neutral connector prior to connecting each power conductor when connecting the load to either power supply.

    摘要： A portable electric tool has a switching device for reversing the direction of the current through the motor to reverse the motor. The switching device comprises two pairs of contacts which extend in cantilever fashion from a circuit board, a rotatable shaft having axially spaced apart terminals thereon, and the terminals being electrically insulated from the contacts by insulating collars secured to the shaft. Each collar has a window therein for access to the respective terminal, the contacts being resiliently biased against the collars with one of each pair of contacts engaging a respective terminal through the respective window in one direction of rotation of the motor and the other of each pair of contacts engaging the opposite respective terminal through the respective window in the opposite direction of rotation of the motor. A shoulder on the shaft may have flats to prevent rotation of the shaft while the trigger of a trigger-switch is actuated.

    摘要： Phase reversal switch apparatus for a three-phase high-current isolated phase bus circuit includes a non-reversing phase switch, and two groups of two reversing phase switches. The apparatus also includes a phase reversal mechanism having a rotatable operating shaft with a drive lever, a non-reversing lever, and two reversing levers coupled thereto. Locking and drive couplings are selectively engaged with the levers and operated by a shift actuator and a switch actuator to selectively operate the non-reversing switch and the first and second reversing switches to effect a phase sequence reversing operation in a secure and efficient manner.
