Method of Preventing Static Charge Shock

A method is described for controlling the harmful effects of operator- induced static electricity which occurs when the operators of electronic equipment who have an electrostatic charge on their bodies use the equipment.

Modern electronic equipment contains electrostatic sensitive devices. Memory chips, for example, can be destroyed or damaged by the static discharge of electronic equipment operators during normal use. Current solutions to this problem include special floor mats, carpets, and desk tops, and static bracelets. All of these devices need to be touched before and periodically during the operation of the word processor, computer, video game joysticks, etc., to drain the static charge harmlessly to grou

To more effectively dissipate this static charge, ON/OFF switches, spacebars, keys, joysticks, and if necessary, cases are made from a plastic with very high electrical resistance properties (e.g. between 27,000 ohms and one megohm per one qua (1/4) inch). When the operator turns on or uses the equipment, the static charge on his/her body is dissipated by the high resistance path to the chassis ground supplied by the new switches, keys, etc.
