Alternate Tile Set for Mah Jongg Tile set name: SCHEMATK.TIL Subject: Schematic symbols used with PADS-LOGIC schematic drafter Created by: Thomas Taylor PADS-LOGIC is a program which allows a printed circuit board designer to create a circuit representing the desired components. This circuit is then used as input to another program in which the actual printed circuit board layout is accomplished. The following list of symbols are ones which I use in my system and are mostly commonly used representations. The tiles are: 1. Switch,SPST 18. N type MOSFET 2. Switch,DPST 19. P type MOSFET 3. Switch,Normally Open PB 20. NPN transistor 4. Switch,Normally Closed PB 21. PNP transistor 5. Coil 22. Diode or rectifier 6. Transformer 23. Potentiometer 7. Relay, SPDT 24. Zener diode 8. Connector 25. Operational Amplifier 9. Off Page connector 26. Silicon Controlled Rectifier 10. NAND gate 27. +5 volt power 11. NOR gate 28. Circuit ground 12. Buffer (non-inverting) 29. Earth ground 13. Inverting buffer 30. Chassis ground 14. AND gate 31. Resistor 15. OR gate 32. Light Emitting Diode 16. P type Junction FET 33. Capacitor 17. N type Junction FET 34. Battery 35. Microphone \ 36. Speaker | first wildcard 37. Meter | set 38. Personal Logo / 39. Square Wave \ 40. Triangle Wave | second wildcard 41. Sine Wave | set 42. Sawtooth Wave /
