FEATURES
 Universal Test Socket accepts devices on 0.300 to 0.600 [7.62 to 15.24] centers
 All pin count sockets go into PCB with either 0.300 or 0.600 [7.62 to 15.24] centers
 Swing quick-release handle down to open contacts and insert device. Release and
handle automatically returns as contacts close onto device leads
 Socket handle can be mounted on either the right or left side
 Sockets can be soldered into PCBs or plugged into any socket
