Mercury is better, the conductivity of the mercury switch contact resistance between the electrodes is less than 100 m Ω commonly. (4) mercury switch allows current depends on the electrode materials, tungsten electrode for the maximum allowable current 10. A, the general wire normally maximum allowable current 1 a. (5) due to gravity to determine mercury switch on and off by mercury, so it can work reliably for a long time.

Using voltage: ac 110 v to 220 v The maximum power: 2000 w Voltage regulation: ac 50-220 - v Size: high temperature resistant FR - 4 PCB circuit boards around 36 mm x 48 mm Outside dimensions: 48 mm * 60 mm (knob) * 28 mm (high) Accused of silicon pressure up to 1200 v/current 25 a 1.6 mm thickening epoxy copper-clad boards Take the product string in desk lamp or desk lamp of the electrical circuit, (namely, the desk lamp, electrical appliances such as broken wire or any root of the zero line, two wires connected to the "product" as well as) rotating potentiometer rod, can play to adjust light and shade, speed, pressure regulating, the effect of tempering; It is very convenient to use.
