Abstract
A rocker switch having a spring-biased lock lever within the contact actuator that extends out to catch beneath the rim of the hole in the frame to lock the rocker button in the 'off' position. An insertable key, which may include the entire face of the rocker button, has a projecting cam effective when inserted to retract the lock lever to allow normal operation. Removal of the key prevents unlocking of the rocker switch for operation to 'on' position. The lock lever has an angular end that allows actuation of the rocker button from 'on' to 'off' position even when the key is removed. This angular end cams on the frame to momentarily depress the lock lever and allow it to snap below the rim of the hole in the frame. This lock lever is then inaccessible except to the projecting cam of the key.
