Electrical Schematic Symbols And DefinitionsHarness And Wire Electrical Schematic Symbols A AA T Pressure Symbol Temperature Symbol Level Symbol Flow Symbol Typical representation of a Deutsch connector. The plug contains all sockets and the receptacle contains all pins. Receptacle Plug 1 2 1 2 1 2 KENR2856 December 1995 Typical representation of a Sure-Seal connector. The plugand receptacle contain both pins and sockets. Pin or Socket Number Wire, Cable, or Harness Assembly Identification Normally open switch that will close with an increase of a specific condition (temp-press-etc.). Component Part Number Single Wire Connector Normally open switch that is closed due to an applied condition, and will open again with a specific decrease in that condition. C A A 325-PK-14 Pin AA 1 Wire Color Socket Normally closed switch that will open with an increase of a specific condition. 2 Normally closed switch that is open due to an applied condition, and will close again with a specific decrease in that condition. 9X-1123 325-PK-14 200-BK-14 Circuit Number Identification The circle indicates that the component has screw terminals and a wire can be disconnected from it. Wire Gauge Electrical Schematic Symbols And Definitions FUSE - A component in an electrical circuit that will open the circuit if too much current flows through it. No circle indicates that the wire cannot be disconnected from the component. This indicates that the component has a wire connected to it that is connected to ground. This indicates that the component does not have a wire connected to ground. It is grounded by being fastened to the machine. REED SWITCH - A switch whose contacts are controlled by a magnet. A magnet closes the contacts of a normally open reed switch; it opens the contacts of a normally closed reed switch. T CB-634C Vibratory Compactor Electrical System 3BR1-UP SENDER - A component that is used with a temperature or pressure gauge. The sender measures the temperature or pressure. Its resistance changes to give an indication to the gauge of the temperature or pressure. RELAY (Magnetic Switch) - A relay is an electrical component that is activated by electricity. It has a coil that makes an electromagnet when current flows through it. The electromagnet can open or close the switch part of the relay. CIRCUIT BREAKER (C/B) - A component in an electrical circuit that will open the circuit if too much current flows through it. This does not destroy the circuit breaker and it can be reset to become part of the circuit again. SOLENOID - A solenoid is an electrical component that is activated by electricity. It has a coil that makes an electromagnet when current flows through it. The electromagnet can open or close a valve or move a piece of metal that can do work. MAGNETIC LATCH SOLENOID - A magnetic latch solenoid is an electrical component that is activated by electricity and held latch by a permanent magnet. It has two coils (latch and unlatch) that make electromagnet when current flows through them. It also has an internal switch that places the latch coil circuit open at the time the coil latches. © 1995 Caterpillar All Rights Reserved Printed in U.S.A. 105-3542 26 - 200-BK UNUSED 3 1 200-BK 330-YL UNUSED 123-WH 10 3 BRAKE SWITCH 116-5275 122-7344 116-6565 WARNING HORN SWITCH 155-PK 109-OR 10 176-YL IGNITION SWITCH 9G-7641 VIBRATION FUSE 3K-8782 173-YL B 15 110-GN-14 ST BRAKE FUSE 3K-8782 2 NEUT START 777-PU 103-YL S UNUSED 112-PU-6 ON 308-YL 326-PU 307-OR 105-BR AUTO-VIB SWITCH (FWD) 155-PK 308-YL 155-PK 568-GN SHIELD C 105-BR R OFF AUTO-VIB SWITCH (REV) C932-YL WATER SPRAY FUSE 8M-8948 121-YL CIRCUIT GROUPING DESIGNATION INDICATOR LAMP 2N-2371/ 2V-7087 4 C934-BU 330-YL P7 1 C934-BU P27 R10 BACKUP ALARM PRESS SW 9D-7032 10 P6 5 DUAL AMPLITUDE HARNESS 120-8868 7 8 6 1 4 2 3 5 9 10 11 12 5 123-WH C932-YL 155-PK C933-GN 326-PU 330-YL 308-YL 13 24 200-BK UNUSED UNUSED 19 33 R10 330-YL UNUSED 5 4 7 8 6 1 4 2 3 5 9 10 11 12 308-YL DIAGNOSTIC LIGHT CLUSTER 117-5674 117-5673 P10 326-PU 3 16 B921-WH 121-YL 777-PU FUNCTIONAL LIGHT CLUSTER 405-GY 428-OR C931-OR 123-WH 465-OR 406-PU 14 7 B440-GN 1 B920-GN 321-BR F E D C B A 1 2 C933-GN 322-GY 635-BR C932-YL C930-BR 200-BK B438-OR 614-PU 3 200-BK 200-BK 123-WH 400-GN 2 AUTO/MAN.
