Abstract
A self biased isolated remote switch (11) for electrically isolating a switch (24) from a circuit (16). The circuit (16) is coupled to the primary side of the self biased isolated remote switch (11) while the switch is coupled to the secondary side. The secondary side does not need a power source, power is provided through non-electrical coupling from the primary side. The self biased isolated remote switch (11) comprises a first circuit (13) and a second circuit (14) both on the primary side, and a third circuit (12) on the secondary side. The first circuit (13) non-electrically couples to the third circuit (12) for providing power. The third circuit (12) non-electrically couples to the second circuit (14) for indicating when the switch (24) is closed.
