Abstract
A voltage detector includes a cylindrical hollow body housing including an open end and a tool end. An internal circuit assembly includes a voltage sensing loop, a flashlight, and a microprocessor. The internal circuit assembly is disposed inside the cylindrical hollow body housing. The voltage sensing loop is configured to detect voltage without contacting a detected voltage, and the microprocessor is configured to control power to the flashlight via a flashlight power button independently from power to the voltage sensing loop via a voltage detector button.
Claims7
A control system for a voltage detector having a voltage detector circuit and a flashlight circuit comprising:
- a first stage, the first stage corresponding with a deactivated voltage detector circuit and a deactivated flashlight circuit;
- a second stage, the second stage corresponding with an activated voltage detector circuit and a deactivated flashlight circuit;
- a third stage, the third stage corresponding with a deactivated voltage detector circuit and an activated flashlight circuit;
- and
- a fourth stage, the fourth stage corresponding with an activated voltage detector circuit and an activated flashlight circuit,
- wherein the first stage is a default stage, and
- wherein:
- user action is required to transition from the first stage to any one of the second stage, the third stage, and the fourth stage, and
- user action is required to transition from the second stage to the fourth stage.
