SWITCH

2. BE REMINDED TO OUR CLASS
ROOM RULES
•You are not allowed to leave the class when the class
is going on.
•Ask questions if something that is not clear to you.
•Always follow the direction of the activity, if you

4. Basic Function of Switch
• To open and close a circuit
–Open (not connected)
–Closed (connected)
• Control device
–Does not consume power

5. • Pole- what the switch
armature is connected to
• Throw- the closed position of the
switch
Pole Throw

6. What are the types of switched?

7. Single Pole, Single Throw
• It is the most common type
of switch use to control
lights
• SPST
• 1 pole, 1 throw

8. Single Pole, Double Throw
•It has two stationary
contact & one moving
parts.
•SPDT

9. Double Pole, Single Throw
• It has two stationary contact and
two moving parts attached to the
opposite terminal.
• DPST

10. Double Pole, Double Throw
• DPDT
• 2 poles
• 2 separate closed
positions

11. What will be the purpose of this
lesson
 At the end of the lesson you should be
able to understand and perform a circuit
using two 3-way & one four-way switch

12. PRESENTATION ON HOW A 3-WAY & 4-WAY
SWITCH WORK TOGETHER?

13. Three-Way Switch
• It has three terminals
usually with one pole
• It is a type of switched
that is used to control
light/group of lights in
two locations.
