1. General Safety Precautions
Complex interlock systems are provided when several separate circuits must be opened for safety. Because electrical and electronic equipment may have to be serviced without deenergizing the circuits, interlock switches are constructed so that they can be disabled by the technician.

2. High Voltage Safety Precautions
To illustrate the results of unsafe practices and to re-emphasize the need for good safety habits, particularly around high voltage or high current circuits, consider the following incident.

3. Grounding Of Equipment
It normally carries no current, but is used only when the tool insulation fails, in which case it short circuits the electricity around the user to ground and protects him from shock.

4. Shock
Electric shock is a jarring, shaking sensation resulting from contact with electric circuits or from the effects of lightning.

5. Motor Controls
Switches come in many sizes and configurations, but basically they all perform the same function; switches interrupt or apply power to a circuit or series of circuits.

6. Solid - State Devices
When enabled by a small gate voltage, a triac will permit current to flow in both directions (hence the back-to-back diode configuration in the diagram), making it suitable for use in ac circuits.

7. Multivoltage AC / DC Power Supply
Switch S2 is an SPDT toggle or slide-type which in the position shown short circuits diode CR so that the output will be ac.

8. Capacitor, Relay, And Motor Control Testers
The time you spend building these circuits will be well spent, since they will give you unequivocal responses to knotty problems.

9. Lubricants
WD-40 is a reasonably good preservative and can be used to remove moisture from motors and circuits. .

10. Hand - Held Dryer
Troubleshooting When testing through the circuits to discover a defective part, open the soldered connections to isolate the part and obtain a true test.
