Dual lighted rocker switch embodying a printed circuit board
First Claim
1. A lighted rocker switch comprising:
- a rectangular housing having a hollow cavity defined by opposite, longitudinally extending side walls;
a rib disposed in the internal periphery of the housing;
a rocker disposed in the housing for pivotal movement around a transverse axis and having a portion protruding outside the housing for controlling operation of the switch, the rocker having openings in its external surface for transmitting light, the rib acting as a stop to prevent the rocker from making undesired electrical contact between electrical terminals of the rocker switch;
a cover coupled to the bottom of the housing, the cover having an indented side comprising a flat surface with a ridge around its external periphery, and an opposite side having three generally elongated channels, wherein two of the three channels are spaced apart and the other channel spans the area between the two channels;
a printed circuit board disposed on the ridge around the indented side of the cover inside the housing, the printed circuit board having a plurality of openings disposed therethrough;
a plurality of light bulbs coupled to the printed circuit board at opposite ends of the printed circuit board for emitting light through the openings in the rocker;
a pair of end terminals disposed in the printed circuit board between the plurality of light bulbs, the end terminals having tabs for coupling to electronic circuitry, the end terminals having ridges thereon that provide for contact with a switching mechanism;
a center terminal disposed between the pair of end terminals on the printed circuit board, the center terminal having a tab that provides for coupling to external electronic circuitry, the center terminal being adapted to couple to the switching mechanism;
a switching mechanism having a contact adapted for pivotal movement on a portion of the center terminal, the contact adapted to control conduction of the switch by providing an electrical connection between the center terminal and one end terminal; and
a follower for providing pivotal movement of the contact, the follower having one end coupled to the rocker and the other end having a cone shape for controlling movement of the contact, the follower comprising a spring for controlling desired pressure between the rocker and the contact.

Abstract
A dual lighted rocker switch having a printed circuit board. Bi-pin terminated bulbs and conductive terminals are connected to a printed circuit board to form a sub-assembly. The sub-assembly is placed upon a cover, which is then slid in to place in a housing. The housing has a rib that acts as a stop to inhibit movement of a rocker which would cause the switch to short directly across the terminals of an external battery. The printed circuit board and cover improve the durability of the rocker switch. The printed circuit board is provided to make the assembly of the rocker switch easier. Thus the design of the switch provides for a reduction of cost and time in production of the rocker switch.
