WW Series
The WW Series switching mechanism is a non-snap double break shorting bar type construction. One, two or three circuit versions are available. The three-circuit unit has two poles. On a three-circuit switch in the unoperated condition (see drawing) circuit #2 is closed and circuit #1 and #3 are open. As the plunger is depressed, circuit #2 opens and circuit #1 and #3 are closed. The switch is two-pole since it makes and breaks two separate circuits (#1 and #3). When the plunger is released, circuit #1 and #3 are broken and circuit #2 is closed.
