Product Description: 

Sip/Puff Switch and Sip/Puff Breeze are used to access all manner of switch-activated devices, including speech generating devices, computers, tablets, mobile phones, environmental control systems, and other devices designed for switch scanning.

Sip/Puff Switch

This model is a dual pressure switch using a simple twist-on pneumatic connector that can be connected to any user interface solution. It contains a simple switch closure over a standard 3.5-mm connector.

Sip/Puff Breeze

This model builds on the original sip and puff switch and computer interface solution by adding the capability to generate Apple iOS Switch Control events. It contains a USB output.

Main Features: 

These features are common to all models:

  • Sip and puff pressure thresholds are approximately three inches of water column below and above ambient pressure.

Sip/Puff Switch includes these additional features:

  • All user interface solutions can be attached to the separate, dual pressure switch using a simple twist-on pneumatic connector.
  • Open contacts that close when the user sips or puffs on an attached mouthpiece.
  • Low-voltage and low-current signaling switches are designed for connection to an electronic device.
  • One connector provides both sip and puff events with a stereo cable.
  • Simple slide switch can be used to change the sense of Sip and Puff signals on the stereo connector.
  • Passive pressure switches do not require batteries or external power.
  • Enclosure has integrated "sip" and "puff" test switches.
  • Two standard options for positioning the mouthpiece: a headset and a flexible shaft with a universal clamp.

Sip/Puff Breeze includes these additional features:

  • All user interface solutions can be attached to the separate, Breeze sensor using a simple twist-on pneumatic connector.
  • The electronic pressure sensor in Breeze will sense a sip or puff and convert these events to mouse button clicks or joystick button presses, and pass these to the connected USB host device (typically a PC or Mac computer).
  • Mouse button emulation.
  • Joystick button emulation.
  • Extremely low latency.
