PC/Case Mount Battery Contacts

June 21, 2018
Keystone's spring contacts ensure low contact resistance.

Meeting demands for higher energy, lower weight cylindrical battery components, the latest coil spring contacts are designed to slide into molded cases with no wire lead - direct placement onto a PCB.


Engineered with a contact design that adjusts to variations in battery length, these contacts ensure low contact resistance and dependable connectivity by adjusting to variations in battery length.  These new contacts also offer the convenience of being drop in replacements for standard leaf spring contacts.  Contacts accommodate cylindrical batteries styles including A, AA, AAA and CR2 cells, virtually eliminating the need to specify brand and style.


 Manufactured from .024 in. (.61 mm) thick, steel wire and supplied with nickel plating for superior performance in today’s high tech devices.  Supplied in a positive contact style (Cat. No 243 or 180) or negative contact style (Cat. No 242 or 179) and in a dual contact style (Cat. No 244 or 181).  Availability is from stock through Keystone’s global distribution network.


A major manufacturer of SMT and THM battery hardware, Keystone supplies battery and coin cell holders, clips, straps and retainers in a broad range of sizes and types, along with an extensive array of electronic interconnects and hardware.  In addition, in-house, application engineering services are maintained to meet special product modifications or custom designs with active stamping, machining and assembly support.
