Abstract
In one embodiment, a capacitive switching system may include a plurality of capacitive switches and at least one processor. Each of the capacitive switches may include an activation surface offset from an energized conductor by a dielectric region and a capacitance that is dependent upon an electric field generated by the energized conductor. The at least one processor may execute machine readable instructions to transform a change in the capacitance of one of the capacitive switches into a first control signal indicative of a first active state. A rejection delay may be activated by the at least one processor after the change in the capacitance of the one of the capacitive switches. The rejection delay can remain activated for a predetermined time period. A second control signal may be prevented from indicating a second active state while the rejection delay is activated.
