Hand-held circuit tester with lens arrangement for viewing indicator lamps housed within the tester

摘要

A hand-held electrical tester for checking the wiring of a wall receptacle. The blades of an electrical terminal protrude from one end of a housing which contains indicator lamps and electrical connecting means between the lamps and blades. Thus, the lightining of each lamp or combination of lamps indicates a predetermined wiring condition of a wall receptacle in which the terminal blades may be inserted. The housing is shaped to provide oppositely disposed push/pull surfaces to facilitate insertion and removal of the tester into and from a wall receptacle. The housing further includes compartments at one end thereof, each having a three-sided opening with a generally U-shaped lens disposed therein. Each of the compartments contains a lamp which can be viewed from the top, bottom and end of the tester.
