1. I have to search for switch which has three positions: off, medium, high. Voltage is 220Vac & current is around 400mA.
Off means no connection to load, medium means connection to load via a diode in series & 220v ac main(half wave), & high means entire main connection to load.
2. I have found a switch from local market as in attached pdf. But it has four positions. It has total 10 pins on it. 5 on each side.
There is one common connection on each side, which make connection with other 4 terminals, as switch is toggled.
3. What do these switches called, are these Dual pole 4 throw?? I am looking for three position switch. i dont know what name to search for these switches? I need this kind of switch whose handle is on top as in attached pdf.
