Abstract
A sub control panel for use in maintenance work has a control switch, enable switches and manipulation prohibition members. The sub control panel is configured such that the control switch is not activated unless the enable switches are being kept ON by one hand of the operator and the operator is prevented by the manipulation prohibition members from manipulating with the one hand from turning ON the enable switches. When the sub control panel is to be used, the operator must use both hands and is hindered from inserting both hands to a driven part of a machine to be subjected to maintenance work when the machine is operating.
