DEFINITION

Classification: 340/825.89

Switching element:

(under subclass 825.85) Subject matter wherein the semiconductor changes between two distinct conductive states in accordance with the value of an applied signal.

(1) Note. The signal-causing switching may be applied across a normally conductive path, or may be applied at an auxiliary electrode.

(2) Note. The two states are often conducting and nonconducting.
