What are the specifications of Push Button Switch?

The specifications of push button switches can vary significantly based on their intended use, design, and manufacturer. However, here are some common specifications and features that you might find in push button switches:

1. Type: Push button switches come in various types, including momentary or latching, normally open (NO) or normally closed (NC), illuminated or non-illuminated, tactile or non-tactile, and single-pole or double-pole.

2. Voltage Rating: They have specific voltage ratings indicating the maximum voltage they can handle safely. Common voltage ratings range from a few volts to several hundred volts, depending on the application.

3. Current Rating: Similar to voltage ratings, push button switches have current ratings that indicate the maximum current they can handle without malfunctioning or overheating. Current ratings typically range from milliamps to several amps.

4. Contact Configuration: This specifies how the internal contacts are configured—whether they are single throw (ST), double throw (DT), single pole (SP), double pole (DP), etc. These configurations determine how the switch connects or disconnects the electrical circuit.

5. Operating Force: For tactile push button switches, the operating force required to actuate the switch (pressing force) and the tactile feedback it provides are important specifications. This can vary depending on the switch design and application.

6. Durability: Switches have a specified number of cycles for their lifespan, indicating how many times they can be pressed before potential failure. This durability rating is crucial, especially in applications where switches are frequently used.

7. Environmental Rating: Some push button switches have specific environmental ratings for factors like temperature, moisture resistance, dust resistance, and other environmental conditions. This information is crucial for selecting switches suitable for particular applications or environments.

8. Mounting Style and Size: Push button switches come in various sizes, shapes, and mounting styles (panel mount, surface mount, etc.). The dimensions and mounting specifications are essential considerations for installation purposes.

9. Termination Type: This refers to how the switch connects to the circuit or wiring, such as solder terminals, screw terminals, or quick-connect terminals.

10. Additional Features: Some push button switches may have additional features such as LED illumination, multiple button configurations, keylock switches, momentary or maintained action, and more.

These specifications and features are essential considerations when selecting push button switches for specific applications, ensuring compatibility, reliability, and safety within the intended electrical circuits or devices.
