Abstract
A switch including a housing carrying a first contact defining a first fulcrum and having an elongated electrically conductive lever blade disposed in overlying relationship and carrying a second contact from one end thereof for normally engaging such first contact. A third contact is carried from the opposite end of such blade and is movable through a predetermined path to engage a fourth contact carried from the housing and defining a second fulcrum. Biasing means is provided for normally biasing the second and third contacts into engagement with the respective first and fourth contacts. An actuator is operative to overcome such biasing means to disengage the second contact from the first contact and is further operative to, in case the first and second contacts become welded together, sufficiently overcome such biasing means to disengage the third and fourth contacts.
