Product Selection and Specifications

Q1: How do I choose the right switch type for my application (Tactile Switch vs. Non-locking Switch vs. Microswitch) ?

A: This depends on your circuit's functionality and operational requirements. Tactile switches provide momentary contact—closing

the circuit when pressed and opening it when released—and are commonly used for functions such as resetting or menu selection.

Self-locking switches latch their state (closed) when pressed once, and reset (open) when pressed again; they are suitable for use as power switches.

Micro switches typically feature a snap-action mechanism and a short travel distance, making them ideal for precise position detection or limit sensing.

Please provide your voltage/current load specifications, desired mode of operation, and lifespan requirements, and we will recommend the most suitable model for your application.

Q2: What is the difference between the electrical life and the mechanical life of a switch ?

A: Mechanical life refers to the number of times a switch can be operated normally under no-load conditions.

Electrical life refers to the number of times a switch can reliably make and break a circuit under its rated load.

Electrical life is typically significantly shorter than mechanical life, as it is affected by contact arcing and material wear.

When selecting a switch, please ensure that both of these life specifications meet the requirements of your specific application.

Q3: A single series of switches offers a variety of mounting heights and operating forces (e.g., 100gf, 160gf, 260gf) to choose from;

how should I determine the combination that is best suited for my product ?

A: 1. Based on "Height"—Determining PCB Layout and Aesthetics:

• Low-Profile (e.g., 2.5mm): Ideal for ultra-thin devices (such as portable smart hardware and Bluetooth earbud cases);

helps minimize overall product thickness while enhancing portability and aesthetic appeal. Typically features a shorter travel distance.

• Standard/Mid-Profile (e.g., 5–7mm): The most common choice, offering ample travel distance and operational clearance.

It is easy to assemble, highly compatible, and suitable for the majority of consumer electronics and industrial controllers.

• High-Profile (>10mm): Designed for applications involving thicker panels or specific structural requirements,

ensuring the button protrudes sufficiently through the panel for convenient operation.

2. Based on "Actuation Force"—Determining User Experience and Reliability:

• Light Actuation Force (e.g., 100gf): Delivers a light, responsive tactile feel. Ideal for scenarios involving high-frequency, rapid operations

(such as game controllers or musical instrument keys), as it helps minimize user fatigue. However, it is important to note that an excessively light

force may lead to accidental triggering under conditions of strong vibration or impact.

• Standard Actuation Force (e.g., 160gf): Offers an optimal balance. It provides clear tactile feedback and effectively prevents most accidental

operations without requiring excessive physical effort from the user. This is the recommended choice for the majority of general-purpose applications.

• Heavy Actuation Force (e.g., 260gf or higher): Provides a solid, reliable tactile feel. Suitable for safety-critical applications where preventing accidental

triggering is paramount (such as emergency stop buttons or critical function switches), or for industrial and automotive environments likely to be subjected to

significant shock or vibration. Requires the user to apply deliberate force to actuate.
