This question relates to wiring a dimmer switch.

What does the symbol next to L2 represent? I assume from looking at other switches that this is the "common" connection.

Should i wire the switch as follows:

This is how i intend to wire the switch

    Read the dimmer switch's datasheet. – Brian Drummond Oct 18 '16 at 12:28
  • Dimmer switch did not come with a datasheet, that was the first place i looked. – user74847 Oct 18 '16 at 12:36
  • So, did you check online for the data sheet? – Andy aka Oct 18 '16 at 12:46
  • I'm voting to close this question as off-topic because it ought to be on DIY Stackexchange. – JRE Oct 18 '16 at 12:46

Do NOT wire it that way.

This PDF shows the proper way to wire that type of dimmer.

  • So is the tilde arrow symbol common? Figure 2 looks like what im after and what i proposed. – user74847 Oct 18 '16 at 12:48

    Your diagram seems to show ground going to L2. The "tilde" is a representation of AC, and the arrow means it is variable. – JRE Oct 18 '16 at 12:51
  • the ground is a separate connection, thats just bad diagram drawing. – user74847 Oct 18 '16 at 12:55
  • + to JRE, it is not a common symbol but I have seen it a few times in the past. It is common to see an arrow through a resistor , capacitor or coil to show it is variable. – Ed Beal Oct 18 '16 at 19:04

L1 and L2 are "Line 1" and "Line 2" (so HOT and NEUTRAL of the AC line). The tilde with the arrow through it symbolizes the adjusted AC. This is the HOT OUT (the dimmed output). Connect the light between the adjusted AC output and Neutral.
