| A three-pole disconnect switch includes a crossbar which is rotatably mounted to a housing and pivots three movable contact blades between opened and closed positions. Each movable contact blade is removably mounted to the cross-bar and makes slidable electric contact with a connector. When in its closed position, each movable contact blade makes electrical connection with a stationary line contact. Modular arc chutes are slidably received in mating cavities formed in the housing above each set of contacts and a pair of auxiliary contact cartridges are received in chambers formed in the housing between the main contacts. A trip mechanism is mounted to the side of the housing and couples one end of the crossbar to a manually operated handle. | ||||||

| An electric switch in the shape of a knob arranged for mounting on the end of a mechanical control lever, the knob being in two parts of which one is rotatable to perform an electrical switching function. The switch is preferably spring biassed to a ''normal'' position by a compression spring lying between the two parts.
