Control Panel Dimensions for Gloved Operation Study 2: Toggle Switches MinimumSpacing Required between Toggle

摘要

This study was to confirm the military specification of toggle switch spacing forgloved operators. An examination of toggle switch operations with five different glove types was conducted: a butyl and cotton glove assembly, a butyl and nomex glove assembly, a leather and wool glove assembly, a fire-fighting glove, and a vinyl glove. Subjects were required to operate a sequence of four switches in a 3 by 3 array. Three switch spacings were investigated: 15 mm, 20 mm, and 25 mm. Half the subjects operated toggle switches located directly in front of them, and the other half operated switches located behind them, in a position where the switches could not be seen. Subjects were required to activate the toggle switches in specific sequences as quickly and as accurately as possible. The task was machine-paced, and the time allowed for operation of a sequence of switches became progressively shorter as the subject was able to continue correct operation. Each subject performed the task both gloved and bare-handed. Toggle switches, Gloves, Control panels, Human engineering, Testing, Chemical protective clothing.
