Claim:
1. A sensor, comprising: a first electrically conductive element having a first diameter on a proximate portion of the first electrically conductive element and a second diameter on a distal portion of the first electrically conductive element; a second electrically conductive element having a first diameter on a proximate portion of the second electrically conductive element and a second diameter on a distal portion of the second electrically conductive element; an electrically insulative element connected to the first electrically conductive element and the second electrically conductive element, where at least a portion of the first electrically conductive element and at least a portion of the second electrically conductive element make contact with the electrically insulative element; and at least one electrically conductive spring located within a cavity of the sensor, wherein the cavity is defined by at least one surface of the first electrically conductive element, at least one surface of the electrically insulative element, and at least one surface of the second electrically conductive element, wherein the at least one electrically conductive spring is connected to an inner surface of the second electrically conductive element and is movable inside the cavity between a first position not contacting the first electrically conductive element, and a second position in contact with an inner surface of the first electrically conductive element.
