  • Circular tactile keypad
    Patent number: 5701123

The keys are marked with numeric indicia in sequential numeric order from 1 to 12, each switch being radially spaced 30-degrees apart. Some of the numbered keys may be replaced with other symbols as desired. Tactile key-finding ridges emanate from the center of the circular key pattern, extending in the direction of each key. The keypad may be releaseably affixed to a trigger grip stand, comprising a planar base and a vertical handle having a trigger switch which when depressed transmits preselected signals to the electrical device.
