Hubbell Toggle Snap SwitchesThe Hubbell Toggle Surface Switch differs from the or-dinary snap surface switch in that manipulation is by thethrow of a lever or toggle, instead of by the turning of a keyor button. Throwing the lever up makes the circuit; throw-ing it down breaks the circuit. The movement is positive—the make and break quick and snappy. The advantages of the toggle movement in a surfaceswitch are three-fold—first, it permits making the switchmore attractive and stronger than the ordinary switch; sec-ond, manipulation is much more convenient by means of the. Exterior of toggle switch with view of the interior of the single poleand three-way type lever than by the turning of a key; third, the switch is self-indicating, the position of the lever showing at a glancewhether the current is on or off without any marker ordial. Electrically, the Hubbell Toggle Surface Switch con-forms with the most rigid requirements of current , it is amply strong to resist the most severeduty—special care having been given to selection of materialsand proportioning of parts to assure the utmost dependability. It combines in unusual degree the best mechanical andelectrical features, with an appearance which makes quickappeal to those seeking the dignity of simplicity and rich-ness.
