TPC21RGPC0

Pushbutton Switches, more specifically the TPC21RGPC0, have many different applications besides its intended push-button switch use. The variety of features and the compact form factor make the TPC21RGPC0 highly versitile, and the wide availability makes it a particularly popular choice for many applications.

The TPC21RGPC0 is an illuminated momentary push-button type subminiature toggle switch, that generally has three terminals. It is a highly reliable switch, and it is RoHS compliant. The push-button is a momentary action, as the switch makes contact while the button is depressed, and breaks contact when it is released. Illumination is provided by an LED, allowing easy identification of the switch\'s status.

The TPC21RGPC0 has an operating temperature range of between -25 and +85 C, and an IP68 rating for dust and water-proofing. The wide available voltage range of 0.4-12V DC makes it suitable for a variety of applications. The switch has a lifespan of more than 100,000 times, a contact resistance of 30 mΩ max and contact current rating of 0.3A. In addition, the switch requires a low operating force of 450g.

The corrosion-resistant switch is made up of an ABS housing, a POM actuator, and a silver alloy contact. The compact form factor makes it well-suited for miniature applications, where space is at a premium, such as game controllers and smart-home devices. The TPC21RGPC0 is also used in a variety of other applications, such as vehicles (car-door switches), generators, vending machines, and electrical switches.

In order to understand the working principle of the TPC21RGPC0, it is important to consider the three terminals. The switch has a common terminal, connected to whichever side the switch is being used on. This terminal is shared by the other two terminals, and is the lead that the current travels through when the switch is depressed. The other two terminals on the switch can be used in a variety of different ways, depending on the application. One terminal can be used as an input, while the other is used to control the action of a device.

The TPC21RGPC0’s design allows it to be used as an input device, or can be used to control the action of another device. In the former case, pushing the switch will cause a current to be passed through the common terminal, while in the latter case, two separate currents will be passed through each of the two other terminals. When the switch is depressed, it will allow the current to flow, thus activating the device. When the switch is released, the current is stopped, and the device returns to its default state.

In summary, Pushbutton Switches, such as the TPC21RGPC0, have a wide variety of applications and features. Its small form factor, wide voltage range, and long lifespan makes it an ideal choice for applications where space is a premium, and where reliability and durability are highly important. Understanding the working principle of the three terminals helps to unlock the possibilities of the switch, enabling it to be used as a switch, an input device, or to control other devices.
