ABSTRACT:
A switch actuating mechanism for use with electrically powered machine tools or related equipment which includes an electrical junction box in which is mounted an "on-off" toggle-type switch, the box having pivotally mounted thereon a broad surface member which is mechanically linked to the toggle lever of the switch. A releasable latch normally holds the broad surface member in a first orientation in which the switch is in its "off" position, but when manually operated, it permits the broad surface member to be swung to a second orientation in which the toggle lever is moved to the switch "on" position. An inward force anywhere on the broad surface member will move the switch lever back to its "off" position and relatch the broad surface member to the junction box. Further included is a key operated lock which is arranged to prevent unauthorized personnel from actuating the switch from its "off" to its "on" position.
