TOGGLE SWITCH LEVER LOCK Abstract of the Disclosure An off-lock for a toggle switch of the type having a slotted guide plate and a spring-biased toggle lever having flats on opposite sides of the portion thereof extending through the elongated slot in the guide plate to confine the toggle lever for non-rotatable pivotal motion. The lever lock consists of arcuate grooves around the toggle lever slightly above the guide plate deep enough to allow rotation of the toggle lever after it is pressed down to bring such grooves to the level of the guide plate. For off-lock in its center off position, the toggle lever is pressed down against the force of the plunger springs and turned 90 degrees so as to cause the opposite edges of the slot in the guide plate to mesh with the arcuate grooves and thus lock the toggle lever against pivotal movement. To release the off-lock, the toggle lever is turned 90 degrees whereupon it snaps up to normal position allowing pivotal movement.
