Abstract:
A double-throw switch comprises: a housing; a push button that is mounted for movement with respect to the housing; a first stationary terminal; a second stationary terminal; a moveable terminal that, when in contact with the first stationary terminal, closes a first circuit, and when in contact with the second stationary terminal, closes a second circuit; a first set of one or more positive stops that engage the first stationary terminal; and a second set of one or more positive stops that engage the second stationary terminal. The first set of one or more positive stops applies pressure to and maintains a predetermined position of the first stationary terminal. The second set of one or more positive stops applies pressure to and maintains a predetermined position of the second stationary terminal.
