Background

Pushbutton switches are a type of switch used to input and output data and control signals. They are widely used in many applications, such as controlling the operation of electronic equipment and controlling the flow of data and power in electronic circuits. This article will discuss the application field and working principle of one particular type of pushbutton switch: the 702PB2.

Application Field

The 702PB2 is a sealed, high-reliability pushbutton switch. It is specifically designed for use in harsh environments, such as in outdoor or marine applications, or in applications where the switch needs to operate in extreme temperatures or wear and tear. The 702PB2 is ideal for applications that require long life, durability, and reliability. It is available in a variety of form factors, including surface-mount, panel-mount, and desktop. The 702PB2 is ideal for applications that require both long life and high reliability. It features a sealed design that provides protection against dust, moisture, vibration, shock, and other harsh environmental conditions. The 702PB2 is also suitable for applications that require a large number of switches, as it can be used to control multiple inputs and outputs with only one switch. Its sealed design also makes it suitable for applications that require a high degree of protection from the elements, such as in outdoor or marine applications.

Working Principle

The 702PB2 is a single-pole, double-throw (SPDT) pushbutton switch. It operates by changing the position of the internal switch contact when the actuator button is pushed. The internal switch contacts can be arranged in one of two ways; either normally open (NO) or normally closed (NC). When the internal switch contacts are in the NO position, the switch is open and no current is flowing between the two terminals. When the switch is closed, either by pushing the actuator button or by other means, current flows between the two terminals.The 702PB2 also has a momentary-on function, which allows the switch to remain in the closed position only when the actuator button is pressed. When the actuator button is released, the internal switch contact moves back to its original position, allowing the switch to open. This momentary-on feature can be used to control a variety of electronic equipment and signals.

Conclusion

The 702PB2 is a reliable, high-performance pushbutton switch that is designed specifically for use in harsh environments. It features a sealed design that provides protection against dust, moisture, vibration, shock, and other harsh environmental conditions. The 702PB2 is ideal for applications that require both long life and high reliability, and it is available in a variety of form factors. The 702PB2 also has a momentary-on feature that can be used to control a variety of electronic signals and equipment.
