The microwave oven timer is a mechanical timer, which can adjust time from 0 minutes to 180 minutes. Ordinary microwave ovens generally use electric timers with timing ranges of 30min, 60min, and 120min. The timer switch is combined with a power control switch and is driven by a miniature permanent magnet synchronous motor. Although the timer switch is closed after the set time, it does not work immediately. Only when the main and auxiliary interlock switches are turned on, the miniature synchronous motor will drive the small-modulus gear transmission to run and play a timing role. When the set time is over, the timer contact is automatically opened to cut off the working power of the microwave oven. At the same time, the steel bell was struck by a pendulum, and a crisp bell sounded.

The other features of the mechanical timer
1. It would cut the power and stop the control system when working time to be ended;
2.Single current system. ON--OFF;
3.Nicely precise construction to minimize the operation trouble to almost zero, high-temperature resistance;
4. The timer will be stopped after an alarming voice. (turn off)
