ABSTRACT:
A pivoted-actuator safety switch of the type having a spring-biased lock lever within the sub-actuator that extends out to catch beneath the rim of the hole in the switch frame or housing to lock the pivoted-actuator in its "off" position, and a removable insertable actuator, covering the sub-actuator, has a projecting cam effective when inserted to retract the lock lever to allow normal operation, but removal thereof prevents unlocking of the sub-actuator and thus prevents operation from "off" to "on". A half-guard integral with the frame guards the actuator in "off" position to meet the "palm test", that is, it cannot be turned on accidentally by bumping or striking with the palm of the hand, while providing open access to the actuator in its "on" position so that it can be quickly turned off. This half-guard consists of upstanding plates integral with the frame on opposite sides of and extending higher than the actuator in "off" position. Lateral projections on the pivotal actuator enter slots in these plates to render the actuator non-removable in "on" position but allow removal in "off" position.
