The “USB Pendant Button” is a hand-held switch on a USB cable. A press on the button sends a keystroke (or a mouse button click) to the workstation. You can configure which keystroke that is. You can use the USB Pendant Button to perform any command on the workstation: launch a presentation, start a show, pause or resume playback, or any other action.

The button has a robust metal casing, and is available with either a nickel-plated or (black) powder-coated surface.

The USB Pendant Button is recognized by the PC as a “keyboard” —with only a single key. Microsoft Windows (and other operating systems) have intrinsic support for these devices. The USB Pendant Button runs out of the box, no driver is needed (on tablets with a USB “On-The-Go” connection, an adapter-cable is needed).

CE & FCC compliant
USB Pendant Button


The USB Pendant Button is a robust hand-held switch on a 3 meter long cable. A “debounce” circuit avoids false triggering and an ESD protection filter on the USB input guarantees a reliable operation.

As mentioned above, the PC or workstation recognizes the USB Pendant Button as a keyboard with one key. The key to transmit to the PC is configured via a free configuration utility, 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. By default, the USB Pendant Button transmits the keyboard key “1”.

In addition to single-key transmissions, the USB Dome Button supports “macro commands” which allow 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.

Multiple Pendant Buttons may be attached to a PC at the same time, with each Pendant Button (typically) configured to transmit a different key code.
