Distinctive Characteristics Miniature Toggles Antirotation design, standard on noncylindrical levers, mates toggle and bushing; bottom of toggle has two flatted sides which fit into a complementary opening inside bushing. Antijamming design protects contacts from damage due to excessive downward force on actuator. High torque bushing construction prevents rotation or separation from frame during installation. High insulating barriers increase isolation of circuits in multipole devices and provide added protection to contact points. Molded diallyl phthalate case has a UL flammability rating...
