Connectors for lnfinite Switch
• Easy insertion, positive locking
The combination of terminal and housing
allows easy mating to a male tab. Un-
mating is equally easy. Simply hold the
housing and pull. The contact locking
spring is depressed by the taper inside the
housing. The locking mechanism prevents
accidental disengagement of the contact
from the mating tab.
• Ultra low insertion force
The contact is designed as a low insertion
force with a large contact area to give
stable performance, even when high
current is applied.
• Contact back out preventive design
Innovative contact and housing design
eliminates contact back out caused due to
damaged locking lances during termination
and harness assembly.
• Polarizing rib
Polarizing ribs in the housing eliminate
miss mating of the housings.
