under normal circumstances, when the electronic circuit is closed, the full name of the arc flame will be generated between the contacts. the larger the total current is, the easier it is to cause arcing, the slower the contact changing speed, and the longer the arcing delay, which are all factors that lead to the deterioration of the contacts.
the snap-action mechanism of the micro-switch can instantly change the contacts, so the arc delay is short. although the specifications are small, it can be used as a power supply circuit with a very large total current.
2. precision machining
the microswitch can basically change the contacts at the same position even if it continues the on/off operation process, so the position detection error is small, and it can be used in the scope of application that requires precision machining. this is also the unique advantage of the micro switch with snap action mechanism.
potential.
3. performance indicators
due to the short arc delay time, the damage to the contacts is relatively small, so the performance index has been improved.
4. touch and sound
the snap-action mechanism has abnormal touch and sound during operation, so the operation process can be defined according to the feel and auditory system software.
characteristics of large, medium and small micro switches
1. pocket, lightweight and precision machining.
2.m3 mm type with utility screw.
3. in addition, the special-shaped terminal and standard spacing structure are adopted, so that the welding wire and flux cannot penetrate into the inside of the power switch.
4. it is also necessary to have a low-power power circuit type (au cable sheath point contact) that can be loaded with a minimum current intensity.
5. independent terminals, which are beneficial to be installed on the printed package board. the main body of the power supply is separated from the printed package board with a diameter of 1.2 ~ 1.6 mm.
6. the product series of the right corner terminal and the left corner terminal of the printed package board are also required.
