A switching probe is conductively connected to the barrel, spring and receptacle while the terminal is insulated from these components and is designed primarily for detecting the absence or presence of non-conductive features, where a normal contact probe can not be used.
Typical Uses
Tip: Prevent damage to the insulator on the tail by using heat sinking pliers during any soldering.
Insulated head probes are used for circuit board component lead detection and testing. The insulating shroud is raised slightly higher than the metal serrated tip. During test, if the component lead or connector pin is set correctly, the electrical contact will be made. Pins absent or misaligned will cause the shroud to make contact first and fail the test.
