ABSTRACT:
A conformal electrical sensor switch for determining the presence or absence of weight, such as a person in a bed, comprises flexible, parallel sensing strips positioned to make contact when pressure is applied. Sensing strip circuits are held apart by a separator strip until pressure is applied and thus closing a latch which provides signal output through snap connectors which are affixed to the sensing strips and which extend beyond the sealed flexible cover of the sensor switch. The flexible cover serves to secure the sensing strips and connectors in a facing relationship. The connectors are designed to permit easy attachment to a variety of signal processing/monitoring devices.
