Switches

Switches are used for a number of different functions in hearing instruments, and Sonion’s big selection of different Switches covers them all.

For Behind-The-Ear (BTE) devices, the traditional Rotary Switch gives the end user the possibility to select input source between microphone and telecoil.

For both In-The-Ear (ITE) and Behind-The-Ear (BTE) devices, switches like push buttons are needed to change between the different programs in the hearing instrument.

Toggle switches are used for on/off or for Microphone/Telecoil selection.
