ABSTRACT:
A portable electric power tool incorporates in conjunction with its double-pole main switch mechanism (11) a separate carrier member (10) which carries two pairs of terminals (20; 41) for the attachment of the main electric leads and the motor stator leads. Four pairs of complementary connectors (23, 24, 32, 33; 48) are also provided, the two connectors of each pair being mounted one on the carrier member (10) and the other on the switch mechanism (11) and the four connectors on the carrier member (10) are respectively connected to the terminals (20; 41). The carrier member (10) is appropriately located in the tool and has two posts (44) which become engaged in apertures (45) in the body of the switch mechanism (11) as the mechanism (11) is placed in position. The connectors (23, 24, 32, 33; 48) of each pair are so disposed that the act of positioning the switch mechanism (11) in this way brings the connectors (23, 24, 32, 33; 48) of each of the four pairs into engagement.
