Touch pushbutton switches have been used extensively in consumer electronics and industrial applications for decades due to their ease of installation, low cost, and reliable operation. The PB-12631ZG pushbutton switch is one of these devices, serving as a commonly used device for starting, stopping, or resetting various functions in consumer or industrial settings. Rather than using an electromechanical contact, the PB-12631ZG uses capacitive sensing to register a pressed switch state. The capacitive sensing eliminates contact wear and thereby increases reliability and reduces maintenance costs.

The PB-12631ZG switch is designed with a wide variety of applications in mind. It is typically used in machines, electronic device accessories, and other industrial applications wherever a simple single button input is desired. The device has a wide operating range and can work in temperature ranges from -20°C to 80°C, making it suitable for many applications in harsher industrial environments. The pushbutton switch also carries RoHS, UL, and CSA certification to ensure that it can be used in many different settings.

The PB-12631ZG switch utilizes a type of capacitive sensing known as "open capacitive sensing." This means that the capacitive detector is separate from the contacts on the button, allowing for a "no-contact" operation of the device. The capacitive detector is connected to a voltage source through its series resistor, and then to the outside ground. When the switch is pressed, the electric field around the capacitor increases, and the capacitor\'s plate capacitance also increases, resulting in a decrease in the input impedance of the circuit. When the impedance drops below a predetermined value, an electrical signal is sent to an output line, signaling the switch state.

In addition to basic switch operation, the PB-12631ZG comes with a variety of options to increase its application flexibility. It can be programmed with a variety of timing functions, such as debounce delay, latching or momentary operation, and a single or double-click feature. It also provides the option of connecting external devices, such as LED indicators or buzzers, via its electrical connectors. The LED indicator can be used to provide visual feedback on the switch state, and the buzzer can be used to alert the user of a switch being actuated.

The PB-12631ZG is one of many touch pushbutton switches on the market and is an excellent choice for a variety of applications. It offers a reliable contact-less operation and a wide array of options and timer functions, making it suitable for different applications in the consumer and industrial environments. The wide operating temperature range, certification to safety standards, and other features make this switch a great option for a variety of pushbutton switch applications.
