This universal test socket is designed for easy insertion and removal of devices such as PROMs and EPROMs without damaging their pins. It features an integral lever that, when in the vertical position, opens the socket holes for easy placement of the IC. Moving the lever to the horizontal position securely clamps the pins, locking the device in place. The socket accommodates ICs with pin pitches of 0.3 inch, 0.4 inch, and 0.6 inch, making it versatile for a wide range of devices.
