IP67 Micro Switch for Automotive Applications

G3 Automotive Micro Switch For Benz 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 Microswitch 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 automotive micro switch is watertight with an IP67 rating, often used in automotive applications due to its sealing ability and quick mounting option.

 

Automotive Micro Switch Principle

Automotive micro switch sets in the car 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 rotary the door handle. At the same time, 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 an close state. At last, The door lock will be open.

Today cars, especially 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. Usually, we named G3 sub-miniature microswitches automotive micro switches. Unionwell G3 micro switches waterproof grade is IP67. The microswitches avoid the rainwater entry into the car door inner lock microswitches structure inside to cut the circuit.

 

Types of automotive switches

The parts of the car have applied the widest variety of microswitches. These automotive switches can be classified into the following groups:

Sealed microswitches

 

We have known that G3 sub-miniature microswitches 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 microswitch 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 microswitch. Meanwhile, the microswitch must quickly snap action and have a long service life.

 

Value to customer

Value – the right switch for a specified application at a competitive price. Greetech matches product performance with customer design expectations.

Customization – various actuators, terminations, wire connections, 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 for 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 types of 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 microswitch. It meets the car industry standard.

 

Potential applications for switching automotive

For use in applications where a pre-wired sealed on/off switch is required. 

Medical – Medical and hospital beds, foot pedal controls, and chair lifts.

Industrial – Appliances, communication equipment, computers, electromechanical timers, mechanical cam assemblies (timers), office equipment, electric tools, HVAC wall controls, instrumentation, valves, vending machines. 

Transportation – Automotive, truck, and boat wire harnesses; sub-assemblies for convertible roofs; lock modules for tail-gate/trunk. 

We can provide flexible and high-quality solutions to assist in designing electronic units. We have various switch technologies so that designers and engineers can design and manufacture the cars they want. Our high-quality switches extend the life expectancy of the application.

What is a micro switch?

The micro switch is a contact mechanism with a small contact interval and a snap-action mechanism and a contact mechanism that performs the switching action with a specified stroke and a specified force. Small, hence the name micro switch, also called a sensitive switch.

 

Classification of microswitches

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, dust-proof, and explosion-proof types; Single type, double type, and multi-link types.

There is also a strong disconnect microswitch (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 type, 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℃)

Microswitches are generally based on unassisted pressing accessories as the basic type, and small stroke types 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 such as button type, reed roller type, lever roller type, short boom type, long boom type, and so on.

(1) Small microswitch

(2) Ultra-small microswitch

(3) Super small microswitch

(4) Waterproof mciroswitch

 

How the microswitch works

The external mechanical force acts on the action reed through transmission elements (pressing pins, buttons, levers, rollers, etc.). An instantaneous action occurs when the action reed is displaced to the critical point, making the moving contact at the end of the action reed and the fixed contact point switch on or off quickly.

When the force on the transmission element is removed, the action reed generates a reverse action force. When the reverse stroke of the transmission element reaches the critical point of the action of the reed, the reverse action is completed instantaneously.

The contact distance of the microswitch is small, the action stroke is short, the pressing power is small, and the on-off is fast. The action speed of the moving contact has nothing to do with the action speed of the transmission element.

Unionwell microswitches have obtained UL, ENEC, CQC, and other international certifications and passed ISO9001, IATF16949, and ISO14001 quality system assurance.
