Communication switching
A communications switch directs data through a switched network. Data moves from its source to its destination through a series of network nodes.
Adaptive communication switches
Adaptive switches allow people with physical difficulties or particular access needs to activate assistive-technology devices within their environment.
A suitable switch can provide access to communication devices, environmental controls, computer software and mobile equipment through an apparently simple button interface.
