ABSTRACT:
A female power contact which is energized only upon insertion of a male plug. The contact includes a plunger which is biased toward a position which blocks accidental finger insertion into the contact. The plunger also contains sharp points on its outer edge to further prevent accidental finger insertion into the contact. However, insertion of the male plug into the female power contact, against the spring bias, causes the plunger to depress the spring in order to produce an electrical connection between the male plug and female contact.
