US 2026/0063671 A1 · POWER SUPPLY PROBE WITH POLARITY SAFEGUARD

Abstract

A system and method provides for safeguarded selection of a polarity for selected application of power or ground to a test circuit via a circuit tester test probe. A positive polarity selection switch is aligned with a negative polarity selection switch on a probe surface. A virtual switch indicia is shown on a probe display with an actuation axis of the virtual switch oriented to correspond to relative alignment of the polarity switches. Pressing the positive polarity switch places the virtual switch in a first position indicating a positive probe polarity selection and pressing the negative polarity switch places the virtual switch in a second position indicating a negative probe polarity selection. Additional polarity selection indicia are generated to reinforce user recognition of a selected polarity to avoid circuit or probe damage.
