Electronic feeler gauge

A gauge for confirming that a gap between a first surface and a spaced apart, opposed second surface is set a predetermined distance, comprising:

• a power source;
• an indicator coupled to said power source;
• and
• a switch having a first plate member and a second plate member such that said power source is connected to said indicator when said first plate member is in contact with said first surface and said second plate member is in contact with said second surface, said switch coupled to said power source and said indicator, wherein said switch operates to power said indicator with said power source when said gap is set to said predetermined distance, and wherein said switch operates to not power said indicator with said power source when said gap is not set to said predetermined distance.

A method for adjusting a gap between a first surface and an opposing second surface comprising:

• a. inserting a switch into the gap in a first direction, wherein the switch comprises a first plate coupled to a second plate,
• b. moving said switch in a second direction,
• c. determining whether the gap is set to a predetermined distance by repeating steps (a) through (b) and checking an indicator,
• d. adjusting the gap,
• e. repeating steps (a) through (d) until the gap is adjusted to the predetermined distance, wherein the indicator comprises an electrical circuit comprising a power source coupled to the switch such that when the switch is closed, the power source powers a light emitting diode, and when the switch is opened, the power source does not power said light emitting diode,
• f. placing the first surface of the gap in contact with the first plate,
• g. placing the second surface of the gap in contact with the second plate such that the first plate contacts the second plate, and
• h. passing a current through the first and second plates such that the electrical circuit can power the light emitting diode.
