The whole process of the work of the micro switch is: when there is no external force, the on-off and on-off isolating switch are in a stationary state. 

When the external force is released from the external transmission rod, the bow spring is caused Deformation, storing mechanical energy and causing deflection. 

As the zero point of the order is reached, the spring leaf is connected to the moving isolating switch and causes a momentary jump, which leads to the connection, disconnection or conversion of the power circuit. 

When the external force is eliminated, the spring leaf will release mechanical energy and cause reverse deflection. When another zero boundary point is , the isolating switch will automatically correct under the action of the spring leaf.

Features of micro switch

       1. Although the specifications and models are small, the total flow of large electricity can be switched on and off

   Under normal circumstances, when the electronic circuit is closed, a flame whose full name is arc will be caused between the contacts. The greater the total current flow, the more likely it is to cause arcing, the speed of changing the contact is very slow, and the longer the time delay of the arc is, which is the factor that causes the deterioration of the contact. The snap-action mechanism of the micro switch can change the contacts in an instant, so the arc time delay is short. Although the specification and model are small, it can be used in a power circuit with a very large total current flow.

  2, precision machining

   The micro switch can basically change the contact at the same position even if the opening/closing operation is continued, so the position detection error is small, and the application range that requires precision machining can be used. This is also the unique advantage of a micro switch with a snap-action mechanism.

  3, performance index

  Because the arc time delay is short, the damage to the contact is relatively small, so the performance index has been improved.

   4. Touch and sound

  The quick-action mechanism has unusual touch and sound during the operation process, so the operation process can be clarified according to the hand feeling and the auditory system software.

  The characteristics of small, medium and large micro switches

   1. Pocket size, light weight, precision machining.

  2, m3 mm type with practical screws.

  3. The externally formed connection terminal and the structure with a standard pitch are adopted to prevent the solder wire and flux from entering the inside of the power switch.

  4. A low-power power supply circuit type (au cable sheath point contact) that can be loaded with a small current intensity is also necessary.

  5. Independent terminal block, which is beneficial to be installed on the printed packaging board. The main body of the power switch is separate from the 1.2~1.6mm printed packaging board.

  6. It is also necessary to print and package the right-shaped corner terminal block and the left-shaped corner terminal block product series.

  7, in line with rohs instructions.

What is the difference between a touch switch and a micro switch? 

The general touch method of a touch switch is a click type. The connection is disconnected in an instant, and the function is relatively single. Generally suitable for a single on and off of a microelectronic product (click The function of the micro switch is more diversified. It can be turned on and off into a power circuit, and it can also be used as a detection power switch. Relatively speaking, the cost is relatively high. In other words, the micro switch can completely replace the tact switch. The most important thing is the difficulty of the cost and capacity structure.
