PVA6LRE21111 Pushbutton Switches are designed to provide momentary or alternate action and are available with a variety of physical configurations designed to suit a wide range of applications. Pushbutton Switches are actuated manually, most commonly with a plunger, but also with a rocker arm, key, roller lever, and more, and must be manually reset to achieve their original ON and OFF positions.

Application Field

PVA6LRE21111 Pushbutton Switches can be used for a variety of applications, including operation and control of machinery, such as starting and stopping engines, lighting and ventilation systems, and operation of electronic or electrical appliances, such as automotive and electronic devices. The switches also find use in industrial applications, including equipment protection, medical devices, food processing and packaging systems, and safety equipment. In buildings, these switches are used in elevator systems, fire alarms, and other safety systems.

Working Principle

Pushbutton switches have a pair of contacts, usually held closed by a spring. When the switch is actuated, the contacts open, allowing a current to flow. When the switch releases, the spring restores the contacts to the closed position and the flow of current is stopped again. In an alternate action switch, the contacts open and close with each successive push of the switch, usually reversing the current flow.

PVA6LRE21111 Pushbutton Switches are available in various shapes, sizes and voltage ratings. These include AC and DC rated switches, as well as those with LED indicators for indicating the position of the switch. Pushbutton switches also come with a variety of contacts, such as silver, gold, and palladium-silver, as well as special limits, such as spring return, overload, high power, and high temperature.

Conclusion

PVA6LRE21111 Pushbutton Switches are highly versatile and useful for a variety of applications. They are used for both On/Off and alternate action applications, and have the ability to control any electrical or electronic device, making them a valuable addition to any control system. PVA6LRE21111 Pushbutton Switches are available in various shapes, sizes, and voltage ratings, with a variety of contact materials, making them suitable for most any application.
