Andy, Just happened to be reading a servo drive manual yesterday that I think mentions just the part your looking for. The manual was referring to adding through hole components (resistors and capacitors) for tuning the drive, and goes on to mention these solder free through hole terminals for mounting through hole items that need to be easily inserted and removed without having to resolder them. The part was "Mill Max P/N 8427" it is a single pin socket that you solder into a through hole on a pcb that you can then insert a wire or through hole pin for a solder free connection.

To be perfect for this application the springs would need to be W rather than V shaped. Or, so I think. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." - George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list [email protected] https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.sourceforge.net%2Flists%2Flistinfo%2Femc-users&data=05%7C01%7Ctoddz%40pgrahamdunn.com%7C9d1b6e4d2d894019a5da08da640044e7%7C5758544c573f47cebee96c3e0806fb43%7C0%7C0%7C637932249586426487%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=%2BJSH84Hrc7SDkpseFtayC5xR0QppSQSBtvaZVfSCho4%3D&reserved=0 _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
