Our Switch It Up! Vibrating Switch for the disabled lets you control toys and other switch adapted devices. Switch has vibration feature for increased sensory stimulation. Vibration can be turned off for users that do not need that feature. Can also be used alone as a vibrating experience or plugged into a switch adapted toy or device to act as a switch. Rubber feet assist in keeping the switch from sliding. Button surface area measures 2.75" across and requires approximately 3 oz. of pressure to activate and has slight clicking sound and vibration (which can be turned off) for feedback. The bright colors make it easy to find, especially for individuals with visual impairments. Requires 2 AA batteries (not included) for vibration mode.
