ABSTRACT:
A cordless modular power tool having a battery module, a motor module and a tool module that can be a saw, drill, toothbrush, flosser and the like. First and second electrical plug units are situated on the battery and motor modules respectively. The battery module plug unit is used in a d.c. mode to supply d.c. current to the motor and in an a.c. mode to receive a.c. current for charging the battery. Switching between the two modes is accomplished during plugging and unplugging of the two modules by locating a magnet in the motor module which influences an actuator arm in battery module to do the switching.
