wherein the first member and the second member are configured to slide with respect to each other while the first middle connection bridge is placed between the two second side connection bridges, and the second middle connection bridge is placed between the two first side connection bridges.

8. The pogo pin of claim 2 , further comprising

a second body comprising:

a second stopper protruding from the second body, and configured to prevent the spring from being separated from the second member; and

a second latch protruding from the second body so that the other end of the spring is placed between the second stopper and the second latch.

9. The pogo pin of claim 1 , wherein

the first member including the first body, the first middle connection bridge and the two first side connection bridges is formed of a single sheet material, and

the second member including the second body, the second middle connection bridge and the two second side connection bridges is formed of a single sheet material.

10. The pogo pin of claim 1 , wherein

the first body comprises a first body part serving as a frame of the first member, and a first stopper protruding from the first body part to prevent the spring from being separated from the first member; and

the second body comprises a second body part serving as a frame of the second member, and a second stopper protruding from the second body part to prevent the spring from being separated from the second member.

11. The pogo pin of claim 10 , wherein

the first body further comprises a first latch protruding from the first body part so that one end of the spring is placed between the first stopper and the first latch, and

the second body further comprises a second latch protruding from the second body part so that the other end of the spring is placed between the second stopper and the second latch.

12. The pogo pin of claim 1 , wherein the first middle connection bridge is bent from the first body to form a step therebetween, the step having a greater thickness than the at least one first side connection bridge.
