The Classification Of Led Tact Switch

LED tact switches can be classified based on several characteristics such as their physical design, functionality, and performance. Here is a detailed classification of LED tact switches.

1. Physical Design

a) Surface mount tact switches: These are characterized by having contacts that are directly attached to the circuit board. The switches come in a sealed package making them tamper-proof.

b) Thru-hole tact switches: These have contacts that pass through the circuit board. They can be easily inserted into the board and are mechanically stable.

c) Ultra-miniature tact switches: These are characterized by their small size making them ideal for use in tight spaces or small electronic devices.

d) Waterproof tact switches: These switches have an IP67 rating, making them waterproof and dustproof. They are ideal for outdoor applications.

2. Functionality

a) Single-pole single-throw (SPST) tact switches: These are the simplest types of switches, and they only have one contact. When pressed, the switch is on, and when released, the switch is off.

b) Single-pole double-throw (SPDT) tact switches: These switches have two contacts, and they can switch between two circuits. When the switch is pressed, it connects one circuit and disconnects the other circuit.

c) Momentary tact switches: These switches provide a momentary contact closure when pressed, and they return to their original position when released.

d) Latching tact switches: These switches provide a contact closure that stays closed until the switch is pressed again.

3. Performance

a) Low-force tact switches: These switches require minimal force to actuate, and they are ideal for use in touch-sensitive applications.

b) High-force tact switches: These switches require a significant amount of force to actuate, making them ideal for use in rugged applications.

c) Low-profile tact switches: These switches are designed to be thin, making them ideal for use in applications where space is limited.

d) Long-life tact switches: These switches are designed to perform many actuations before wearing out, making them ideal for applications that require high reliability.

4. Illumination

a) LED-backlit switch: These switches have a built-in LED that illuminates the switch. They are ideal for use in low-light environments.

b) Through-hole LEDs: These switches have a built-in LED that is mounted next to the switch. They are ideal for use in applications where the switch needs to be illuminated.

c) Surface mount LEDs: These switches have a built-in LED that is mounted directly onto the circuit board. They are ideal for use in applications where the size of the switch is critical.

In conclusion, LED tact switches can be classified based on their physical design, functionality, performance, and illumination. Understanding these classifications can help you choose the right switch for your application.
