DUAL BLADE-TYPE CONTINUOUS HIGH CURRENT DISCONNECT SWITCH Abstract of the Disclosure An improved, high voltage, electrical blade-type single-pole disconnect switch is provided which has an especially designed clip or jaw end for maintaining proper electrical contact between the switch blade and adjacent switch terminal even under very high momentary loads. The switch blade is formed of a pair of elongated, laterally spaced, deflectable metallic blade halves which engage, and are deflected laterally by, the terminal contact when the switch is closed; proper blade- terminal contact pressure is maintained by a tension bolt and sleeve spacer arrangement located adjacent the free end of the blade. The releas- able latch for the blade is pivoted thereto at a point closer to the marginal end of the blade than the engagement between the latch and stationary latching clip, such that the latch is pivoted closed (i.e., into firmer engagement with the clip) under the influence of normal electromag- netic forces which tend to pivot the blade to its open position.
