ABSTRACT:
A pressure-sensitive switch apparatus for use in monitoring the position of a patient in a bed or chair is provided. The switch includes a resilient conductor disposed between first and second conductors located at opposite surface areas of the switch. The resilient conductor provides varying degrees of electrical contact between the first and second electrical conductors in response to pressure applied to either of these conductors by shifting of the patient's weight.
