A latch for connecting a switch operator, such as a push button, to contact blocks in an industrial switch employs opposed spring loaded teeth to engage detent surfaces on the operator. The teeth are attached to jaws generally along a line parallel to the line between the opposed teeth but to one side of a sleeve receiving the operator. The jaws and teeth are connected so that separation of the jaws separate the teeth allowing disengagement of the operator. The space between the jaws is accessible along an axis extending toward the back of the switch so as to permit release of the operator by means of a tool such as a screwdriver without clearance about the switch. The teeth may be wedge shaped to permit the operator to snap in place, only, without the use of the tool.
