Switch device

Abstract

A switch device includes a regulating circuit, a loading unit, a battery, an alternating voltage detecting loop and a voltage-increasing loop. The regulating circuit serves to regulate an inputted alternating voltage. The loading unit is connected to an output terminal of the regulating circuit, and operates when receiving a voltage outputted from the regulating circuit. The battery is connected to an output terminal of the loading unit. The battery keeps charging while the loading unit is working. The alternating voltage detecting loop is respectively connected to the regulating circuit and the battery. The voltage-increasing loop is respectively connected to the alternating voltage detecting loop and the battery. When the alternating voltage detecting loop works, the voltage-increasing loop generates oscillation to increase the power of the nickel hydrogen battery and drive the loading unit.
