Dual-Function Switch Replaces Two

The MPL-501-P-V is a unique dual-function switch capable of replacing two separate switches in applications requiring both pressure and vacuum sensing, such as sip-and-puff controls for mouth-actuated devices. The dual-function switch can sense both pressure and/or vacuum input in a common port and will switch two circuits in response.
Actuation ranges can be very low (i.e., under one inch of water column). Ranges can also be made higher as required by the particular application. Recommended ratings are from 10 to 20 mA. The company can configure custom devices for OEM applications.
