and puck keyboard/keypad combination (shown at left in picture below). Current production uses a snap dome switch and
plunger keyboard/keypad combination (shown at right in picture below).
Do not mix assemblies. A conductive trace keyboard PCBA should always be used with a conductive puck keypad. A
snap dome keyboard PCBA should always be used with a plunger style keypad. Units should be repaired with the style of
keyboard/keypad they were originally built with.
