Abstract:
     This switch includes a multiposition operation mechanism which can be locked in each switching position to prevent the reflection of contacts and absorb all closing forces within the mechanism. The switch position indicator can move with the turnable contact. A triposition switch for example, can turn one end of a contact which can turns around an axis to a non-removable contact, to make the contact off set device off the current path, while another end of it being selectively contacted to one of two additional non-removable contacts, yet, the triposition switch still remains an open circuit position of non-contact. The contact turnable around the axis is driven at a middle position between its two end, so that the torque arm is increased, and the force between driving parts and contact-carrier is reduced considerablly.
