Gentle halogen-light switch
The switch circuit, intended for low-voltage halogen lights, extends the life of the lamps, because it ensures that the filament current is increased gradually, thus obviating the high peak currents that flow through the lamp with normal switches. The addition of a timer would enable the circuit to switch the lamp off agam after apreset period of time.
