Types Of Through-hole 6mm Push Button Switches

Through-hole 6mm push button switches come in different types, each with specific features and applications. Here are some of the common types:

1. Momentary switches: These switches are also called "normally open" or "NO" switches. They have a spring-loaded button that returns to its original position when released. When the button is pressed, the contacts are closed, and when it is released, the contacts are open. These switches are suitable for applications that require a temporary connection, such as a doorbell or a flashlight.

2. Latching switches: These switches are also called "normally closed" or "NC" switches. They have a button that clicks into position when pressed and stays there until pressed again. When the button is pressed, the contacts are closed, and when it is pressed again, the contacts are open. These switches are suitable for applications that require a permanent connection, such as a power switch.

3. Illuminated switches: These switches have a built-in LED or incandescent lamp that lights up when the switch is activated. The illumination can be in different colors, such as red, green, yellow, or blue, and can be used for status indication or aesthetic purposes.

4. Sealed switches: These switches are designed to be water-resistant or dust-resistant and are suitable for harsh environments such as outdoor or industrial applications. They have a rubber boot or membrane that covers the button and prevents water or dust from entering the switch.
