High Performance Coil Spring Battery Contacts
These new high performance contacts are drop in replacements for traditional leaf spring contacts. Extremely rugged in design, these contacts are ideal for retaining cells securely under severe shock and vibration in high-density applications.
The coil spring contacts, a principal design feature, assure proper polarity and tension on the installed battery within battery compartments or case designs using cylindrical cells.
Manufactured from Steel with a Nickel Plating, these contacts offer low contact resistance and superior solder joints where lead-free soldering processes are employed.
