Abstract
An assembly of at least two single-pole, double-throw slide switches, with one of the switches being mounted 90.degree. with respect to the other switch. A movable plate is positioned above the two SPDT switches, and the movable plate has apertures or the like which engage the projecting arms of the two SPDT switches, whereby translating movement of the movable plate causes action of one or both of the SPDT switches. Appropriate springs are provided to bias the movable plate to a centered, rest position at all times. Hence, movement of the movable plate as a result of some manual force may affirmatively generate any one of eight distinct signals. The centered rest position of the movable plate may also be considered as a signal-generation position, such that nine distinct bits of information may be communicated through the manual manipulation of a single knob that is connected to only two SPDT slide switches.
