Reversing mechanism for electric motors

摘要

A power tool has a mechanism to reverse a motor. The mechanism includes a first member secured with the motor surrounding the motor commutator. A pair of electrical contacts are supported in the first member. A second member is rotatable on the fist member. The second member carries a pair of brush holders which include electrical contacts. As the second member is rotated in the first member, the electrical contacts of the brush holders, as well as the electrical contacts in the first member, electrically couple with one another from a first position to a second position which relates to a forward and reverse direction of the motor. A lever moves the second member between its first and second positions.
