The Types Of Video Illuminated Pushbutton Switch

Video illuminated push button switches, also known as tactile switches, are popular in various industries, including electronics, gaming, and computing. Their popularity is due to their reliability, durability, and their ability to provide tactile feedback to users.

Here are the common types of video illuminated push button switches:

1. Single Pole Single Throw (SPST) Switch

The Single Pole Single Throw (SPST) switch is a basic video illuminated push button switch. It has two terminals, one for the input and one for the output. SPST switches are used when only one circuit needs to be activated. They are ideal for devices that require simple on/off functionality.

2. Single Pole Double Throw (SPDT) Switch

Single Pole Double Throw switches are similar to SPST switches, but they have two output terminals instead of one. SPDT switches are used when a device needs to be switched between two circuits. They are ideal for devices that require polarity reversal or alternate operation.

3. Double Pole Single Throw (DPST) Switch

The Double Pole Single Throw (DPST) switch is like two SPST switches in one. It has four terminals, two for the input and two for the output. DPST switches are used when two circuits need to be activated simultaneously. They are ideal for devices that require dual on/off functionality.

4. Double Pole Double Throw (DPDT) Switch

The Double Pole Double Throw (DPDT) switch is like two SPDT switches in one. It has six terminals, two for the input and four for the output. DPDT switches are used when a device needs to be switched between two circuits, and both circuits need to be activated simultaneously. They are ideal for devices that require alternate operation and polarity reversal.

5. Momentary Switch

Momentary switches are also known as “push-to-make” switches. They are normally open switches that are spring-loaded to return to their original position when released. Momentary switches are used when a device needs to be activated only when the switch is pressed, and it should not remain on when the user releases the button.

6. Latching Switch

Latching switches are also known as “push-to-on” or “push-to-off” switches. They are used when a device needs to be switched on or off and remains in that state until the switch is manually toggled again. Latching switches can be either SPST, SPDT, DPST, or DPDT.

7. Illuminated Switch

Illuminated switches are push button switches that have a light source to indicate the switch’s status. The lights can be in through-hole, SMD, or RGB LED’s that can also add flexibility and aesthetic flare to the design. The light may indicate if the switch is on or off, or if it is in a different state.

8. Key Lock Switch

Key lock switches are a type of push button switch that is typically used in equipment in which it is desirable to limit access to the switch’s functionality. They look like normal push button switches but have an additional mechanism that only allows the switch to be activated by a specially designed key.

9. Anti-Vandal Switch

Anti-vandal switches are designed for outdoor and rugged environments. They have strong metal or steel casings that protect the switch parts from vandalization or forceful pressure. They have high resistance to water, dust, electricity, and other environmental effects.

Conclusion

Video illuminated push button switches are essential components for devices that require tactile and visual feedback. They come in various types with different specifications that cater to specific industries and applications. Understanding the different types of video illuminated push button switches will help designers, manufacturers, and end-users choose the best option for their needs.
