ABSTRACT:
Electrical contact terminal of the flat coplanar type which is manufactured by stamping sheet metal, has a yoke portion having a latch arm and a spring arm extending therefrom. The latch arm is relatively short while the spring arm is of sufficient length to permit deflection thereof when the terminal is placed in service. The two arms have free ends which are adjacent to and resiliently biased against each other. The free ends are latched to each other by latching means which permits movement of the free end of the spring arm along a side edge of the latch arm. An edge portion of the spring arm serves as a contact portion and current flows from this contact portion to the end of the spring arm then to the latch arm and to the yoke portion of the terminal to provide a short low inductance current path for the current. The spring arm is in a preloaded and flexed condition so that an elevated contact pressure is achieved.
