Abstract
A two-pole switch for DC current has a housing formed by a pair of open shells abutting each other to enclose components of the apparatus. Each shell rigidly holds a stationary contact, and an actuator is pivotally coupled to the shells. A pair of movable contacts are pivotally attached to the actuator so that each movable contact touches one stationary contact when the actuator is in a first position and the contacts are separated when the actuator is in a second position. A spine plate is between the shells and electrically separates the two stationary contacts and arc extinguishing chambers. A solenoid is within the housing aligned with the contacts and drives the actuator between the second and first positions to close the contacts.
