The 120 v that you measure might not be able to carry an appreciable current. If the switch is off and the other measurements might be phantom voltage 20 100 volts.
Surestart Low Voltage Disconnect Switch From Cole Hersee
Low voltage when switch is off. This means that there is a low voltage in the ceiling light even when it is switched off which causes the led to light up weakly. In the off position the light passes a small amount of current through itself to the load. A lighted switch has the light across the contacts. I could still do what i want to do with the rewire to the new location but at the same time it would be nice to have some assurance that all is okay. The switch leg will meausre zero hot to neutral if the switch is on. Because with the switch off the path is through the light bulb and it would return the neutral to the switch and you would get 120 v.
When you close the switch there would be close to zero volts across the switch. I would think it will read 0 volts. Btw if there is power in the ceiling. There are problems with this measurement. 44 out of 5 stars 23. All sockets and other circuits have no problem.
Not enough to activate the load just enough for the light in the switch to work. I doubt it does unless you wired it that way. Twtade 8pcs solder spst onoff mini boat rocker switch 2pin toggle spst switch snap with lines kcd1 x y. Here the voltage carrying conductor can induce a voltage in the conductor separated from the switch. When the switch is off the only way it would be zero is if the switch shorted the inputs together. Where v low is the low voltage shutoff threshold.
Put a 1 meg resistor across the input on the meter to kill stray readings then measure the voltage. Get it as soon as thu jul 9. By proper choice of r1 and r2 this circuit will work well for shut off voltages in the range of about 45 to 10 v. The lighting circuit in my bungalow insists on leaving an odd low voltage on the positive wire when it is switched off. The lower limit is determined. When lights are switched off the positive line shows a consistent but different voltage for each room from 6 volts on spots in the living room and 27 on the main light.
This is perfectly normal and very basic. When either switch is turned on i get 120 volts but when turned off i still get 68 70 volts. Maybe this is normal and i just dont know much about how these shared circuits work. Push button switch waterproof on off light wired switches 12v for motorcyclecar 5pcs black. Amazons choice for low voltage on off switch. This will cause a small voltage to be present at the receptacle.
