167 Electric Push-Button Switch, and Operating Element Having an Electric Push-Button Switch US15267204 2016-09-16 US20170004932A1 2017-01-05 Michael Bleckmann; Tobias Hafner
An electric pushbutton switch includes a pushbutton, a rocker, and a housing. The pushbutton has a substantially rectangular actuating surface. The pushbutton is received within the housing and is displaceable connected to the housing. The pushbutton displaces with respect to the housing by way of a pressure actuation onto the actuating surface, thus triggering an electrical switching element. The rocker is box-shaped and is arranged within the housing beneath the pushbutton body and is at least partially encompassed by the pushbutton. The rocker is mounted on an inner longitudinally extending wall of the housing by a pivot bearing. By actuating the actuating surface, the rocker pivots about the pivot bearing while supporting the pushbutton along the longitudinal extension of the pushbutton.
168 Switches, Switch Arrays, And Keyboards Using The Same US14544701 2014-02-02 US20160042885A1 2016-02-11 Dinh Le
An m-by-n switch array comprises a frame, switches that anchor around the frame, and threads that connect the switches to their opposing sides of the frame. Applying pressure on a thread pulls the switch, connected to that thread, to its ON state and releasing pressure on the thread lets the switch, connected to that thread, bounces back to its natural OFF state. Applying pressure on an intersection of two threads pulls the two switches, that connected to the two intersected threads, to their ON states while releasing pressure lets those two switches bounce back to their natural OFF states. The position of the intersection, where pressure is applied, can be determined by checking the ON/OFF states of all the switches. Keys can be placed on the thread intersections to emulate devices such as keypads, calculators, remote controls, keyboards, and other key input devices.
