Introduction

Pushbutton switches are one of the most versatile and reliable types of switches available. They are designed to provide control over various electrical circuits, as well as other various tasks. The P197 OASB switch is a type of pushbutton that is used for specific purposes and applications. This article will discuss the application field and working principle of the P197 OASB switch.

Application Field of P197 OASB

The P197 OASB is a type of pushbutton switch that is often employed for switchboard configurations. It is suitable for use in almost any type of switchboard layout, as it can be wired in series, parallel, or combinations of both. Additionally, it can be wired to either open- or closed-circuit breakers and manual reset switches.

In addition to its use in switchboards, the P197 OASB can be used in the control of machine tools, automobile parts, computers, and other electrical circuit control systems. It is suitable for controlling the motors, drives, and other components that are typically used in these systems. Additionally, the P197 OASB is often used in conjunction with other switch types to provide reliable triggering, such as when used in conjunction with a SPST switch to provide a toggle function.

Working Principle of P197 OASB

The P197 OASB is a simple switch that makes use of a plunger to open and close a circuit. When the plunger is pressed, the contacts of the switch connect, closing the circuit, and when the plunger is released, the contacts of the switch open, disconnecting the circuit. The switch is designed to be actuated only when physically pushed; it does not contain any type of electronic component or circuitry, thus making it suitable for use in a wide variety of circumstances.

The P197 OASB is a single-pole, single-throw (SPST) switch. It is normally closed, meaning that when the plunger is released, the switch is off. However, it is possible to wire the switch in reversed configuration, with the switch normally open and closing only when the plunger is pressed. The plunger of the P197 OASB is recessed, and it must be pressed for at least a fraction of a second for the switch contacts to connect.

The P197 OASB switch is rated for a maximum of 20A at 125 volts AC and 20A at 250 volts AC. It has a 0.5" mounting hole, and is IP65 rated for dust and water protection. The contacts of the switch are made of silver alloy, and the operating temperature range is -40°F to +185°F (-40°C to +85°C). The switch is usually provided with a black plastic cover, which helps to protect the contacts from accidental contact with conductive objects.

Conclusion

The P197 OASB is a type of pushbutton switch that is designed for use in switchboard configurations and other electrical control applications. It is a single-pole, single-throw switch that is normally closed. It is made of silver alloy contacts and is rated for a maximum of 20A at 125 volts AC and 20A at 250 volts AC. The P197 OASB is also IP65 rated for dust and water protection, and it has a 0.5" mounting hole. This is a reliable switch that is suitable for a wide variety of tasks.
