Abstract: A digital signaling device provides visual, audible, and haptic indicators when the digital signaling device changes state. The digital signaling device has a same operational feel and response as a classic electro-mechanical decorator-style light switch, including maintaining switch paddle position, using attractive magnetic latching in combination with a spring contact. The switch paddle can be pressed into one of two positions, each position representing a different state of the digital signaling device. The switch paddle provides a visual indicator of the digital signaling device state in that the switch paddle is maintained in one of the two positions. The attractive magnetic latching provides both an audible and haptic indicator when the magnet pairs are engaged, which corresponds to a change of state of the digital signaling device. The spring contact provides a digital switching mechanism for changing the state of the digital signaling device.

Abstract: The disclosure is directed to microelectromechanical system (MEMS) switches with multiple pull-down electrodes between terminal electrodes to limit off-state capacitance. In exemplary aspects disclosed herein, a plurality of pull-down electrodes are positioned between the input terminal electrode and the output terminal electrode. The plurality of pull-down electrodes are offset from each other to limit off-state capacitance between the input terminal electrode and the output terminal electrode. The separation between the pull-down electrodes disrupts the off-state capacitive path between the input terminal electrode and the output terminal electrode, thereby further insulating the contacts from each other. Limiting off-state capacitance reduces on-state electrical loss and increases off-state electrical isolation for improved performance.
