How much do you know about the micro switch?

With the daily life of intelligent life, security problem is more and more attention, household intelligent lock locks a shift from the traditional mechanical lock products, intelligent lock is different from traditional mechanical lock, is to have security, and intelligent lock has dozens of internal parts, the micro switch is one of the core parts, micro switch used for detection in the intelligent lock lock tongue, The feedback signal is transmitted to the IC to control the motor, the next article to take you to understand the principle of the microswitch.

1, the size is small but can switch large current

Normally, when an electronic circuit is turned off, sparks called arcs are produced between the contacts. The higher the current is, the more likely it is to produce arc light, the slower the switching speed of the contact and the longer the duration of arc light, which are the factors leading to the deterioration of the contact. The quick mechanism of microswitch can switch contacts instantly, so the arc light lasts for a short time and can be used in circuits with large current although the size is small.

2. High precision

Microswitch can switch contacts in the same position even if repeated open/close operation, so the position detection error is small, suitable for high-precision applications. This is also the unique advantage of microswitch with quick mechanism.

3. Durability

Due to the short arc light duration, the contact is less damaged, so the durability is improved.

4. Touch and sound

The quick-acting mechanism has a unique touch and sound during operation, so the operation can be confirmed by touch and hearing.

Characteristics of small microswitch

1, super small, light, high precision.

2, can use universal small screw M2mm type.

3, using the structure of forming terminals and with reference distance at the same time, so that solder, flux is difficult to invade the switch inside.

4, also equipped with the most suitable for small voltage and current load of small power circuit type (AU cladding contact).

5, self-supporting terminal, easy to install to the printing plate. The switch body is self-supporting relative to the 1.2~1.6mm printing plate.

6, also equipped with printing board right corner terminal and left corner terminal series.

7. Comply with ROHS instructions
