Conductive carbon pill silicone rubber keypad vent

A carbon pill silicone rubber keypad needs its conductive elements aligned with the intended circuit contacts. The molded faces, flexible regions, and base should follow the complete device layout. Any vent or clearance feature specified in the keypad geometry also needs to remain in its designed position.

Check the support beneath each button and the space around the contact region. A key must travel and return without the base shifting across the board. An apparently centered face does not by itself show that the underside has reached the correct location.

Fit the keypad using its locating references and keep contacting surfaces free of particles. Do not cover or modify an opening simply because it appears unused in the loose mat. Evaluate the completed device through individual and adjacent presses. During servicing, inspect the flexible regions and restore the original orientation before checking every control. Use the matching molded and carbon-pill arrangement for replacement rather than selecting a similar keypad only by its visible button pattern.
