Halogen Light Switch Circuit


Posted on Feb 4, 2014

In this halogen switch circuit we use a FET transistor because the current is dependent of the FET`s gate voltage. The maximum gate voltage is 12V, so this circuit is adequate for 12 volt lamps. R1 value is 100 k © for 6V and 470 k © for 12V. You can use BUZ10 which can outstand up to 20A or BUZ11 with maximum 30A. You don`t need heatsink for this FETs because they tend to warm up to only 17 °C.
