Electrical Action Fuzes Flashcards
What are transistors?
Electronic switches and the base leg turns on
What is a Silicon Controlled Rectifier (SCR)?
A Latching Electronic Switch
How does a R/C circuit work?
Timed device with the use of a resistor and a capacitor
What can a photo cell detect?
Light in various spectrums
Presence of or lack of light
What function does the base leg of a transistor do?
It is the trigger / switch
What does a 555 circuit look like?
Spider or Japanese battle flag
What does IC stand for?
Integrated Circuit
What does a resistor and capacitor pair together have in common with a 555 chip?
They are all timing devices
Name a few products that you can find a IC chip in?
Amplifiers - Timers - Oscillators - Voltage Regulators
What are some ID features of a remote control?
Multiple batteries, receiver, braided wire, servos, micro switch, antenna “may or may not be present”
What causes a collapsing circuit to function?
Battery decay, cutting the wrong wire, or anti-disturbance
What causes movement of the contacts in a relay?
The energizing/de-energizing of the coil
What does the photo-cell in a transistor circuit do?
Detects light and allows current to flow through the base leg turning on the transistor
What is a relay?
An electromagnetic switch
What does a PIR switch detect?
Temperature changes in detection zones and movement
