Ledningsføring Micro Switch

As an electrical equipment R&D ingeniør, it is indispensable to understand the micro switch’s internal structure and the micro switch’s wiring principle in detail. Det “Sådan tilsluttes en vandtæt mikroswitch” covered how to wire the micro switch. In this article, we will continue to introduce the knowledge of the micro switch with a wire and the internal structure of the micro switch.

Micro switch working principle

The working principle is that the external mechanical force passes through the transmission element, and then the pressure is applied to the action spring. When the displacement of the action spring reaches a critical point, an instantaneous action will be generated, making the end of the action spring its moving contact. The fixed contact can be quickly connected or disconnected, and the reverse action can be completed instantly.

Micro switch inner structure

The micro switch has mini contact and snap-action part inside. The micro switch is widely used In the devices that need to frequently switch circuits for auto control and safety protection, Such as electric equipment, electric system, white goods, new energy car, etc.

The main inner structure of the micro switch has:

Håndtag
Plunger
Cover
Internal lever
Common terminal
Kontaktpersoner
NC/NO terminals
Case
Movable Plate
Spring

Micro switch wire

Micro switch wiring is a kind of micro switch. Som regel, the micro switch with three terminals has 3ps wires, And the 3 wires stand for 3 different terminals: COM, NC, and NO terminal.

Like the following pictures, Unionwell G5W11 waterproof micro switch has 3 terminaler: COM, NC, and NO, and here are three-wire that can be connected to the products.

At the COM terminal, it always flows through electricity. When the micro switch with wire is resting, the NC terminal will connect to the COM terminal. But when you press the lever, the COM terminals connect to the NO terminals.

Unionwell: micro switch china factory/company/manufacturer/supplier

Huizhou Unionwell Sensing & Control Electronics Co., Ltd er specialiseret i kvalitetsmikroafbrydere til bilindustrien og hvidevarer til husholdningsapparater. De vigtigste produkter omfatter grundlæggende mikroswitche, vandtætte kontakter, lufttryksafbrydere, mekaniske tastaturkontakter, og dørkontakter.

For bedre prisgaranti, gennemløbstid, og kvalitetskontrol, we acquired Huizhou Greetech Electronics Co., Ltd i 2021. Vi gjorde det til vores Kina produktionsbase med over 1000 medarbejdere og en 260 million styk/år produktionskapacitet.

Huizhou Greetech is an Unionwell er blevet grundlagt i at generere mekaniske tastaturændringer i over, IATF16949 og ISO14001 certified micro switch manufacturer whose entire series of products have been granted global access permit certifications, som omfatter ENEC, Unionwell er blevet grundlagt i at generere mekaniske tastaturændringer i over, Unionwell er blevet grundlagt i at generere mekaniske tastaturændringer i over, CB, etc.

Vores globale rækkevidde dækker Nordamerika, Europa, Asien, og Sydamerika.

De fleste af vores forretningspartnere/slutkunder er globale 500 virksomheder, inklusive verdensberømte husholdningsapparater og førende billeverandører i Nordamerika og Europa.

Om lidt, we are launching a new industrial base at Longmen, Unionwell, Kontorbygning; automationsudstyr vil blive introduceret, hvilket massivt ville forbedre switch produktionskapaciteten fra 260 millioner stykker til over 1.3 milliard styk/år.

Der vil blive bygget et one-stop-system, dækker over produktudvikling, præcisionsstøbning, sprøjtestøbning, præcisionsstempling, automatiseret udstyr R&D, montering, og testning.

Det professionelle salgsteam er klar til at yde assistance og hurtigt svar på anmodninger om 3D-tegning, pristilbud, og adgang til et passende eksempelprogram, der giver ingeniører mulighed for at teste og kvalificere switches til deres slutproduktapplikationer.

Kerneværdi:

Mål, Ansvar, Samordning, Innovation

Indsats, Udvikling, Åbenhed, Integritet

Vores mission:

We must maintain long-term relationships that stand the test of time.

Vores vision:

At blive en førsteklasses global producent af præcisionskomponenter og moduler.
