NOTE: GP Series switches are available with screw or solder terminals in U.S. or metric sizes.
*For solder terminals, replace the "T" in the third position of the part number with an "S" (e.g., GPTCND11 becomes GPSCND11).
†For metric mounting, replace the "1" in the seventh position with a "0" (e.g., GPTCND11 becomes GPTCND01).
