How Micro Switches Improve Functions in Electric Scooters

2025-04-08

Electric scooters as a mobility tool used more and more people, the market is getting bigger and bigger, both users and manufacturers should understand the key parts of electric scooters - micro switches, because the micro switches in the electric scooter's power supply system, the safety system and the control of the drive system play a big role.

What is a Micro Switch?

Micro switch is a miniature snap-action switch that responds to very small physical forces. It operates by using a tipping-point mechanism to open or close an electrical circuit quickly and reliably. Due to their fast response and high durability, micro switches are widely used in many electronic and electromechanical devices. In electric scooters, micro switches are often found in control systems where fast and accurate input detection is essential.

What is an Electric Scooter?

Electric scooter is a battery-powered two-wheeled vehicle modern mobility tool , its control mode is the same as traditional electric bicycle, but it is easier to be learned by the driver, equipped with detachable and foldable seat, it is simpler than the traditional electric bicycle structure, small wheels, lightweight and simple, and it can save a lot of social resources.

Features of Electric Scooters

Lightweight and foldable
lithium-ion Battery-powered
Speeds up to 25–30 km/h (some go faster)
Easy to recharge and maintain
Low noise and zero emissions
Often include LED lights, smart displays, and app connectivity

How Does Electric Scooter Work?

The working principle of an electric scooter can basically be divided into the following parts: power system, drive system, and control system.

Power supply system: electric scooters usually use rechargeable lithium-ion batteries as the power source.

Drive system: The drive system includes the electric motor, reducer, and transmission system. The electric motor is the main power source of the electric scooter, which is usually a brushless DC motor.

Control system: the control system is the brain of the electric scooter, which is responsible for monitoring and controlling the operation status of the electric scooter.

How does the micro switch work in an electric scooter?

Brake System

Micro switches play a vital role in the braking system of an electric scooter. When the user triggers the micro switch by stepping on the rear wheel brake, the power chip, once it receives the signal that the micro switch has been triggered, will directly disconnect the battery pack from the motor, ensuring that the brakes are executed accurately, enhancing riding safety and avoiding accidents.

Control of Vehicle Lights

A micro switch is mounted on the fender, and the micro switch detects an indication of movement and recognizes it, controlling the on\off operation of the lighting. That is, when the user presses the fender to trigger the switch member, the method of controlling the scooter's lighting can be completed, thus eliminating the need to set up mechanical buttons and simplifying the structural design of the instrument section.

Safety System

To avoid operating the scooter while it is folded, micro switches are used as sensors to detect the position of the scooter and disable the motor when it is folded.In addition, the micro-switch on the kickstand on the motorized scooter prevents the motor from engaging when the kickstand is lowered, thus avoiding accidental activation.

3 Types of Micro Switches for Electric Scooter

Subminiature Micro Switch

subminiature micro switch is a small and compact size micro switch, that allows it to fit into a variety of tight environments without losing performance. Commonly used in folding lock sensors or throttle control, Ideal for portable devices.

Sealed Waterproof Micro Switch

Some electric scooter micro switches are sealed waterproof micro switches, which are designed for water and dust-tight with an IP67 rating. The IP67 certification is a rating that is fully dustproof and can be submerged in water for 30 minutes, making it very suitable for electric scooters that are used outdoors to withstand inclement weather such as rain.

Basic Micro Switch

The basic micro switch is a standard-size micro switch, with higher current handling and a more rugged build. It is durable with a long mechanical life over 10,000,000 cycles. Commonly Use in Power button and kickstand switch.

FAQ

Q1: How Long Does a Micro Switch Last？

The lifespan of a micro switch depends on its design, materials, and usage environment, but in general, the mechanical life of micro switches is between 1 million to 10 million cycles.

Q2: How Can I Find a Reliable Electric Scooter Micro Switch Supplier？

Unionwell as a China micro switch manufacturer and supplier, has a professional R&D team and our own factory, which can provide high quality and cost-effective micro switch to you.

Q3: How Do I Choose the Right Micro Switch for My Scooter Design?

Choose the right microswitch for your electric scooter according to the size of the use space, whether the use environment needs waterproof and dustproof, built-in circuit and other conditions.
