Abstract

A micro push-button assembly includes a pin which has a head, a shoulder, a neck and a chamfer at the distal end. Other elements include a spring, a washer, and a seal. This unitized push-button assembly has two opposing ends each with distinct functionalities. One end of the assembly includes means extending above the head for press-in captivation with an exterior button while the other end has means for press in captivation with a support member such as a wrist watch chassis. The assembly is provided to the watch manufacturer as a pre-assembled unit with the spring and seal already set onto the operating pin. The final press-fit assembly can be accomplished by hand.
