What is a Continuity checker?

A continuity checker is a measuring device used to verify the continuity of electrical circuits. It quickly and easily determines whether current flows correctly or whether there are issues such as open circuits or short circuits. Commonly used in manufacturing and electrical work, it is beneficial for checking wiring connections, testing circuit boards, and verifying the operation of switches and relays. It typically works by sending a small voltage through the circuit and providing audible or visual feedback if the circuit is properly closed. Its simplicity and portability make it an essential tool for routine maintenance and troubleshooting. Advanced models may also measure resistance and test insulation conditions.

Application of Continuity checker

✅Checking Home Wiring
Quickly verifies proper wiring connections during home electrical installations.
✅Testing Circuit Boards
Inspects the continuity of individual circuits on printed circuit boards in electronics manufacturing.
✅Switch Function Testing
Identifies defective switches and relays in production lines by confirming proper operation.
✅Locating Cable Faults
Finds the exact location of breaks in long cables, reducing repair effort and downtime.
