Pushbutton Switches: TPC11CGRA2 Application Field and Working Principle

Pushbutton switches are the most common type of switches in use today, used in a variety of applications, from toggling power switches to activating other devices or commands. The TPC11CGRA2 is a particular type of pushbutton switch, manufactured by Panasonic, which is designed for high-temperature operation, and can be deployed in highly hazardous or potentially explosive environments. It is well-suited for industrial and military applications. The switch can function in temperatures between -40°C and 85°C, and provides reliable operation during those extremes of temperature.

The TPC11CGRA2 features a 30mm operating stroke, maximum current rating of 10A, and a minimum insulation resistance of 1 Mohm. It also has a high cycles of life (5 million operations) and an ability to withstand 1 million mechanical operations. The switch is rated IP67, meaning that it is able to handle immersion in 1 meter of water. The switch is hermetically sealed, and an external cable is required for power connections.

The TPC11CGRA2 provides momentary operation, meaning that it is not held in the closed position and only operates when the button is pushed. This makes it useful for applications in which the circuit needs to be closed for a brief period to activate a device, such as activating various control systems, such as pressure and temperature gauges, automation systems, or safety alarms. It also makes it a suitable switch for pilot lights, where the light needs to be lit briefly when a button is pressed.

The TPC11CGRA2 is a normally open contact pushbutton switch, which means that it is normally in the open position when not activated. When the button is pushed, it closes the circuit and completes the electrical connection. The switch functions as an instantaneous type, which means that it will instantly switch on and off when it is activated. The switch is extremely reliable and can be used for many years without requiring servicing or maintenance.

The switch is constructed for use in high-temperature environments, and it is designed with several features that ensure its longevity and performance. It has been designed to prevent false switching, and it has a long contact life. The switch is also designed to ensure that it has a low contact resistance, reducing any risk of arcing or damage to components.

The TPC11CGRA2 is a highly reliable and versatile switch, making it suitable for a wide range of applications in high-temperature environments. It is well suited for applications in the industrial and military sectors, where reliable operation and longLasting performance are essential. The switch is also resistant to high levels of vibration and shock, making it ideal for applications in potentially hazardous or explosive environments.
