G3 IP67 Waterproof Automotive Micro Switch For Automobile Door Application
In automotive electronic components, switches are not the most expensive components, but they play an indispensable role in the electronic unit, so they are critical to the success of all projects. The micro switch G3 series subminiature snap-action switches are suitable for applications requiring sensing an object’s presence or absence. For customers who need a switching solution to meet performance and design expectations, the G3 series automotive micro switch offers product configurations at a great value. The G3 series waterproof automotive micro switch is waterproof with an IP67 grade, often used in automotive applications due to its sealing ability and quick mounting option.
IP67 Waterproof Automotive Micro Switch Principle
Automotive micro switch sets in the car’s inner door lock position; the auto micro switch is tinny but has a vital role in the car door lock-control system.
When you prepare to get off, the first action is to open the inner car door, and then you will rotate the door handle. På samma gång, the automotive door handle creates a push action, and the auto micro switch will receive the push force and start work. It will disconnect the circuit to the car door control system and state and close the state. Äntligen, The door lock will be open.
Today, self-driving cars have more computing power than ordinary fighter jets. Many electronic components can use in the engine, drive train, chassis, body system, comfort system, active safety system, and driving assistance system of a car. The value of electronic components is as high as 30% of the total production cost of the car.
Unionwell G3 sub-miniature microswitches are widely used in the automotive inner door lock. Vanligtvis, we name G3 sub-miniature microswitches automotive micro switches. Unionwell G3 micro switches waterproof grade is IP67. The microswitches avoid rainwater entry into the car door inner lock microswitches structure inside to cut the circuit.

We know that G3 subminiature micro switches are widely used in the car inner door lock. G3 micro switch is a small device that can send an electrical signal by a mini-physical actuator. It mainly controls the safety circuit of the machine. For example, the car’s inner door lock applies the G3 micro switch to control the door. Only close the door can the micro switch be released and send an electrical signal to the car control system. Then the car will start the motor and run safely. It requests a high-quality and high-reliability micro switch. Meanwhile, the micro switch must quickly snap and have a long service life.
Value To Customer
Value – the right switch for a specified application at a competitive price. Unionwell matches product performance with customer design expectations.
Customization – various actuators, terminations, wire connections, and operating and electrical characteristics result in thousands of potential configurations.
Reliable – exceeding UL and other agency requirements with repeatability and consistent performance within various conditions.
Environmental protection – can operate under challenging conditions (G3 series are sealed, with an IP67 rating).
Key Features And Benefits Of An Automotive On-off Switch
-Small size and light switches lend themselves to numerous potential applications.
-Choice of low energy or power-duty electrical ratings allows the switch to be specified in more applications.
-Broad range of amp ratings (from 0.1 A to 3 A).
-Watertight IP67 sealing available on some listings allows the switch to be used where sealing and presence/absence detection are required.
-UL, cUL, ENEC, and CE approvals.
-Automotive micro switches usually request 12v dc micro switches or 12vdc micro switches. It meets the car industry standard.

What Is A Micro Switch?
The micro switch is a contact mechanism with a small contact interval, a snap-action mechanism, and a contact mechanism that performs the switching action with a specified stroke and force. Små, därav namnet micro switch, även kallad en känslig switch.
Classification Of Micro Switches
There are many types of micro switches, and there are hundreds of internal structures. According to the volume, there are ordinary, small, and ultra-small; according to the protection performance, there are waterproof, dustproof, and explosion-proof types; Single type, double type, and multi-link types.
There is also a strong disconnect micro switch (when the reed of the switch does not work, the external force can also make the switch disconnect); according to the breaking capacity, there are ordinary type, DC typ, micro, and high-current type.
According to the use environment, there are ordinary types, high-temperature resistant type (250℃), super high temperature resistant ceramic type (400℃)
Micro switches are generally based on unassisted pressing accessories as the basic type, and small and large stroke types are derived. Different auxiliary pressing accessories can be added according to the needs. According to the different pressing accessories added, the switches can be divided into various forms: button type, reed roller type, lever roller type, short boom type, long boom type, and so on.
(1) Small micro switch
(2) Ultra-small micro switch
(3) Super small micro switch
(4) Vattentät mikrobrytare
How The Micro Switch Works
The external mechanical force acts on the action reed through transmission elements (tryckstift, knappar, spakar, rullar, etc.). En momentan åtgärd inträffar när aktionsröret förskjuts till den kritiska punkten, gör att den rörliga kontakten i slutet av rörelseröret och den fasta kontaktpunkten slås på eller av snabbt.
När kraften på transmissionselementet avlägsnas, aktionsröret genererar en omvänd verkanskraft. When the reverse stroke of the transmission element reaches the critical point of the action of the reed, den omvända åtgärden slutförs omedelbart.
The contact distance of the micro switch is small, actionslaget är kort, presskraften är liten, och på- och av går snabbt. Den rörliga kontaktens rörelsehastighet har ingenting att göra med överföringselementets rörelsehastighet.
Unionwell mikrobrytare har erhållit UL, ENEC, CQC, och andra internationella certifieringar och klarade ISO9001, IATF16949, och ISO14001 kvalitetssäkring.
