Panel Mount Keyboard System
First Claim
1. A keyboard system, comprising:
- a keypad comprising;
one or more keys; and
one or more keypad conductive elements for at least one of the keys;
a printed circuit board assembly coupled to the keypad, the printed circuit board assembly comprising;
a printed circuit board comprising at least one switch contact areas for each of one or more keys on the keypad; and
for at least one of the keys of the keypad, one or more first side vias in a switch contact area, wherein the first side vias are electrically coupled on a first side of a switch for the key, and one or more second side vias in the switch contact area, wherein the second side vias are electrically coupled on a second side of the switch for the key,wherein the switch for the key is configurable to close when at least one of the keypad conductive elements bridges at least one first side via in the switch contact area and at least one second side via in the switch contact area.

Abstract
A keyboard system having improved protection from electromagnetic interference includes a keypad and a printed circuit board assembly. The keypad includes one or more keys and one or more keypad conductive elements for at least one of the keys. The printed circuit board assembly is coupled to the keypad. The printed circuit board assembly includes a printed circuit board having at least one switch contact area for each of one or more keys on the keypad. The printed circuit board also includes, for at least one of the keys of the keypad, one or more first side vias in a switch contact area and one or more second side vias in the switch contact area. The first side vias are electrically coupled on a first side of a switch for the key. The second side vias are electrically coupled on a second side of the switch for the key.
