Sip/Puff Switch User Guide
Figure 1: Sip and puff electrical connections on the left and
pneumatic connector on the right.
Two cables are included with the Sip/Puff Switch. Connect a
stereo cable to the center connector if both sip and puff closures
are communicated to the controlled device using one cable.
With connector sense switch to the "left" and a stereo cable, a sip
will cause a closure between the "TIP" and "SLEEVE" and a puff
will cause a closure between the "RING" and "SLEEVE." The right
jack must remain open when using one stereo cable to transmit
both sip and puff events. Slide switch to the right to reverse
contacts on the center connector.
