Keypad Technology in BTE

Idea: Chee Wah Leong, SG-Singapore

Size and quality specifications of electromechanical tact switches of hearing aids, e.g. pushbuttons

and volume controls for BTE (Behind The Ear) devices are gaining importance.

The proposed novel idea consists of using the proven keypad technology which is used, e.g., in

mobile phones. Tact switches used up to now can be replaced (see Figures 1 and 2). This leads to

reduction of size of hearing aids, in combination with a high reliability. Such keypads can easily be

sealed using a rubber dome for activation.

Compared to the current solutions, the proposed solution leads to a reduced inventory and a lower

UMC (Uniform Mechanical Code) cost for the product. Furthermore, the manufacturing processes are

simplified and lead to a faster delivery time.
