Abstract: For electrically connecting an integrated circuit under test to a test circuit board, a test signals conduction device includes a contact member and a spring member. The contact member has a main portion, a contact portion and an extension portion. When the contact portion is pressed by the integrated circuit, the contact portion and the extension portion rotate about the main portion in a first direction, thereby causing the spring member to deform and switch to an energy storing state from a normal state. When the integrated circuit board is moved away from the contact portion, the spring member returns from the energy storing state to the normal state and causes the extension portion and the contact portion to rotate in a second direction.
