PTT control switch kiosk telephone handset A16

For industrial kiosk or PC, it would be much convenient to fix after connecting a handset for communication instead of earphone.With matched stand, this handset could offer signal to kiosk or PC main board to trigger the communication when pick up or hang on the handset.
For outdoor environment noise, we chose different kinds of speakers and microphones for the handsets to match with various motherboard to reach high sensitivity or noise reducing functions; hearing-aid speaker could also be chose for hearing-impaired person and noise reducing microphone could cancel the noise from background when answering calls.
