Abstract

An electrical switching apparatus comprises at least one contact set which includes a pair of contact members resiliently biased towards contact with each other and a body member for removably receiving the contact set in first and second angular senses, for "normally open" or "normally closed" operation of the contact set. An actuator member is movably mounted in the body member and biased in one sense of displacement to hold the contact members apart when the contact set is received by the body member in one angular sense and to permit the contact members to close when the contact set is received in the other angular sense. Displacement of the actuator member, either by electromagnet or manually, causes the contact members to close or to be separated, depending on whether the contact set is received in the one or in the other angular sense.
