A magnetic coupler for use in semi-trailer rigs includes a contact member and a receiving member, the contact member having at least one biased contact which seats in a seat formed in the receiving member, the seat having an electrical conductor disposed therewithin. A member has a peripheral ring of opposite magnetic polarities in order to ensure magnetic attraction therebetween. Cooperating projection and keyway may be formed on the peripheral rings to assure proper alignment between the contact member and the receiving member.
