ABSTRACT:
An apparatus and method for forming an electrical switch assembly by lancing and forming a part of a terminal member through an unblanked part of an L-shaped switch blade member and thereafter staking the lanced and formed part of the terminal member to an adjacent surface of the switch blade member to secure the members together in abutting relation, the apparatus and method having a single reciprocating head that performs the lancing and forming step on a first stroke thereof and performs the staking step on a second stroke thereof. The head reciprocates substantially vertically beneath the abutting members, the head having a top portion for receiving one leg of the L-shaped switch blade and having a side against which the other leg is disposed. The method and apparatus has an arm for holding the other leg of the switch blade against the side of the head.
