Abstract
A socket for establishing electrical connection with a circuit board comprises a dielectric housing having a board receiving slot and a plurality of terminals disposed for engaging respective contacts on the circuit board. The terminals are arranged in at least first and second sets corresponding to respective first and second sets of the contacts on the circuit board. The first set of terminals engages the first set of contacts when the circuit board is inserted into the slot in a first position, and the second set of terminals engages the second set of contacts as the circuit board is pivoted through an angle to a second position. When the circuit board is removed from the socket, the terminals of the second set disengage their respective contacts before the terminals of the first set. Thus, a socket has terminals arranged such that a portion of the terminals provide make first, break last electrical interconnections.
