Abstract

1422326 Socket tester DORMAN SMITH HOLDINGS Ltd 28 March 1973 [22 Jan 1972 7 March 1972] 3127/72 and 10458/72 Heading G1U A socket tester comprises a modified domestic plug 11, Fig 1, including neons, resistors and diodes connected as shown in Fig. 2. When inserted into a correctly wired socket both neons will light. Both neons will also light if the socket is incorrectly wired by having its neutral and earth wires interchanged. Any other wiring fault, however, results in only one or neither neon lighting.
