and those that respond to a grasp, push, tip of the head, or rocking motion.
Some switches make a sound when the switch is activated, or may provide
a movement or texture a person can associate with activation. These devices
can range from a single switch that provides a single message when activated,
multiple switches that provide an increased variety of messages, and/or
a single switch that can be programmed to provide a series of messages
when activated.
Mounts - Mounts keep things in place. A rigid mount works well
for a stationary location, while a flexible mount is ideal for multiple
locations.
