Figure 9 shows the voltage and currents of IGBT switch [S.sub.2] and auxiliary switch
8): The main switch is now carrying the current I and the auxiliary switch
SU is turned on (this switch can already be turned on synchronously to the main switch S.
The augmentative and alternative communication feature may be accessed through voice, touch screen, eye gaze for pupil movement, switch scanning via sip and puff and auxiliary switches
. The device also offers text-to-speech and the use of symbols and/or pictures for functional communication and development.
Other features include a full range of coil voltages, full range of contact combinations, blowout magnet for use between contacts, 10 A auxiliary switches
, and QC terminals to facilitate quick connect terminals for speed in wiring.
