What's the Structure of Mechanical Electric Timer?
The mechanical timer is made according to the principle of the clock mechanism. It uses the mainspring as the power source. In addition to the clockwork, there are three parts including a gear transmission mechanism and a time control component that constitute the timer.
1. Clockwork
It is made of elastic steel belt, and when in use, it relies on manpower to wind up the mainspring through the knob to store potential energy. When the mainspring is automatically relaxed, the stored energy is released, and the power is transmitted to the gear transmission mechanism and the time control assembly.

2. Gear transmission mechanism
According to the different gear clutch modes when winding, mechanical timers can be divided into three transmission mechanisms: spring tube type, pawl type and small spring type.
3. Time control components
The structure of the time control components of various mechanical timers is basically the same. They all use one or two sets of cams to allocate time. When the control cam rotates, its convex and concave positions are constantly changed to make the relevant contacts of the reed according to the design requirements. Turn on or off to control the operation and stop of the motor (or other electrical appliances).
