A sip-and-puff switch is an assistive technology that enables a user to control a device by using their mouth to “sip”(inhale) or “puff”(exhale) on a straw, tube or ‘wand’. It is primarily used by people with limited or no limb movement. The Sip and Puff Switch can be connected directly to an assistive device with a 3.5 mm jack or to a computer or smartphone using a suitable switch interface.
- Battery powered (2x CR2032 Lithium Coin Cells)
- Independently adjustable puff sensitivity and sip sensitivity
- Visual feedback when switch is activated
- Two separate outputs mean that two devices can be controlled.
