Abstract
A unique interlock mechanism for two pushbuttons or other linearly operated devices, requiring no mechanical linkages or complex assemblies. The interlock mechanism essentially comprises an interlock member having first and second restraining portions disposed within a housing so that when one of the pushbuttons is operated, the interlock member rotates positioning itself under the second pushbutton, interfering with and making it impossible to be operated.
