ZIF Socket (20 Pin)

These Zero Insertion Force (ZIF) sockets clamp onto a chip, making a good electrical connection, when you push the lever down. When you release the lever, it releases the chip. This allows you to repeatedly insert or remove a chip from the socket without damage to either. These are great for two situations: When you want to replace the chip that goes in a given place frequently, or when you want to program one chip after another in the same fixture.
