Abstract
A switched telephone tester comprises a tester body defining a connector portion of complementary configuration for receiving a modular telephone plug, a light emitting element responsive to a given voltage for emitting light, and a switch coupled with the tester body and with the light emitting element and movable relative to the tester body to a first position for placing the light emitting element in electrical circuit across tip and ring contacts of the modular telephone plug and a second position for taking the light emitting means out of circuit across the tip and ring contacts, to thereby test for the presence of a voltage across the tip and ring contacts.
