Battery-free Wireless Dome Button
Downloads: Key Configurator utility 2.8.
The “Battery-free Wireless Dome Button” is a palm switch with a large mushroom dome. The Wireless Button connects to a workstation or PC via a USB receiver module, in the form of a “dongle”.
The Battery-free button has an energy harvesting generator, which generates electrical power from the mechanical button press. As a result, the battery-free button does not require any power source, unlike our “Wireless Dome Button, model H0731”. The advantage is clear: there is no need to ever replace or recharge the battery.
The dome is available in several colours.
The USB interface (dongle) is recognized by the PC as a “keyboard”. Microsoft Windows (and other operating systems) have intrinsic support for USB keyboards. No driver is needed (on tablets with a USB “On-The-Go” connection, an adapter-cable is needed). A software utility allows you to define which key (or key sequence) is transmitted to the workstation on a button press.
The Battery-free Wireless Dome Button is a robust and splash-proof “emergency switch”-style button, for indoor and outdoor use. It transmits on the license-free ISM band of 868 MHz (Europe) and 915 MHz (USA, Canada, Australia/New Zealand).
As mentioned above, the PC or workstation recognizes the USB interface as a keyboard. Each connected wireless button is then configured to transmit a key combination (or a key sequence) to the PC. There is a free configuration utility for this purpose, see the Downloads section.
In addition to standard keys, that utility also allows you to configure a few extended functions, such as to function as a “play/pause” button on a remote control, or as a mouse button. You can also configure a button to transmit a sequence of key strokes to the PC, including key combinations with “Alt”, “Ctrl” or “GUI” shift modifiers. With a macro, a press on the button can start an application or open a web browser on a specific URL.
Up to six of these buttons can be connected to a single dongle, with each button (typically) configured to transmit a different key code. It is possible to connect multiple dongles to a PC, in case more than six buttons must be handled.
The base of the button has two holes of Ø5.2mm for mounting the button on a table or wall.
