FIELD: electricity.
SUBSTANCE: invention is related to electric engineering, in particular, to contacts connecting manual electric tool to the battery. Connection structure of contacts ensures additional contacts without increased width of the battery pack and electric device. According to this invention in the connection structure of contacts the battery pack is equipped with a plurality of contacts with different functions placed in sliding direction, and the electric device is equipped with contact for connection with one contact out of the plurality of contacts at the battery pack. By means of relative slip between the battery pack and electric device before a contact in the electric device reaches contact in the battery pack this contact in the electric device may pass through another contact in the battery pack.
EFFECT: increased number of contacts without increased size of the contact pad.
