1 Hour Mechanical timer switch is made of the principle of the clock mechanism. Its working principle and internal structure are mainly divided into the following three parts:
The first part is the power component, consisting of a spring and a one-way structure of the spring, is the power source of the whole timer. When the manual turn the spring to make the spring more and more tight, constantly working for the timer storage potential energy.
The second part is the release part, by a series of gears change speed, so that the number of rotation cycle increase when the spring relaxation, at the end of the gear system escapement wheel, escapement claw and spring. These components ensure that the speed of rotation of the gear under the spring drive remains a constant state. Gossamer with adjusting the length of the device to adjust the escapement claw swing frequency, ensure that the gear according to the set speed of rotation, will not have tightened the law all of a sudden loose, not thin the effect of the law tightness and lead to the change of speed.
The third part is the timing trigger device. When a gear in the gear system turns to a certain Angle, it sends out an electrical signal or mechanical signal, representing that the timer will stop the power supply or send out a bell when the work is finished.
