Lay Me Out Connecting lighting fixture/switches (THREE WAY SWITCH) OBJECTIVES: At the end of the lesson you should be able to: 1. Explain the importance of using a three way switch; 2.Interpret and draw technical plans and schematic diagram; 3. Connect lighting fixture/s in different location using three way switch 3 way switch A switch that is used to control a load in 2 location Where it is used? •Hall way •Stair way •Large rooms •Bed room SYMBOL Switch One line diagram One gang S1 Two gang S2 Three gang S3 Three way S3W Schematic diagram Single Pole Double Throw (SPDT) 1 pole 2 Throws Single Pole Double Throw (SPDT) Single Pole Double Throw (SPDT) 1 0 3 Using the materials below, make a schematic diagram of 1 bulb controlled in 2 location 2 - Three way Switch 2 - Fuse 1 - Bulb Connecting Wire Exercise: Light Me Up Connect the leads correctly using the diagram as your guide. Activity: Draw and Connect Draw and Connect 1. With the same group, select a leader. 2. There will be 2 stations for this activity (1st Station interpretation and diagramming, 2nd Station - connecting the leads) 3. The group leader will assign which station his/her group mate will perform first(2-3 person in a station) 4. After the person/s in the first station is done with the diagram, and once approved by the teacher, the person/s in the 2nd station will now have to connect the leads of the mockup using the diagram as their guide. GROUP 1: 2 bulbs controlled in 2 location and 2 bulbs controlled by 2 single pole switch GROUP 2: Two gang switch controlling 1 bulb each and 1 bulb controlled in 2 location GROUP 3: 3 bulbs controlled by three gang switch and a bulb controlled in 2 location RUBRIC Assignment Electrical Tutor - Make a tutorial video about three-way switch. The video should contain the following: 1. Importance of three-way switch and its application 2. Parts and procedures in connecting the switch.
