    Pushwheel Switches

    Pushwheel switches, also known as thumbwheel switches, are electronic components used for data entry and selection in digital circuits. They consist of a set of rotating disks or wheels, each with several contact pads arranged in a circular pattern. By pushing or rotating the wheels, different combinations of contact pads are brought into contact with a stationary set of terminals, creating a specific binary code that can be read by a digital device. Pushwheel switches are commonly used for inputting numerical data, such as in digital clocks or measuring instruments, and for selecting different settings or options in electronic devices. They can be found in a variety of sizes and configurations, ranging from single-digit to multi-digit switches with up to 10 or more wheels. They are often used in combination with other input devices, such as keypads or touchscreens, to provide a range of input options for users.

    What are the Benefits of Pushwheel Switches?

    Precise data entry: Pushwheel switches provide precise data entry, allowing users to enter numerical data or select options with a high degree of accuracy.

    Simple operation: They are easy to operate and require no specialised training or knowledge.

    Durable and reliable: Pushwheel switches are typically constructed with high-quality materials and are designed to withstand repeated use and harsh environmental conditions, making them a reliable choice for a wide range of applications.

    Low power consumption: They consume very little power, which makes them suitable for use in low-power electronic devices.

    Cost-effective: Pushwheel switches are relatively inexpensive and widely available, making them a cost-effective choice for many applications.

    Versatile: They can be used in a variety of applications, from simple input devices to complex control panels.
