Rotary service switch for the interior of electrical enclosures having a disconnect switch

摘要

A rotary switch assembly for mounting on a disconnect switch ( 10 ) in an electrical enclosure ( 26 ) includes a base ( 50 ) and a rotor ( 60 ) which is rotatably coupled to the base ( 50 ). The rotor ( 60 ) is first axially depressed and then rotated to switch the disconnect switch ( 10 ) to the "on" position. The base ( 50 ) has a stop member ( 53 ) for latching the rotor ( 60 ) in an "off" position before the rotor ( 60 ) is axially depressed. A lockout tab ( 43 ) is attached to the rotor ( 60 ) for locking the switch in the "off" position. A rotary handle ( 30, 90 ) is provided for mounting on the rotor ( 60 ), for operation in either rotational direction. The rotary handle ( 30 ) has two wings with formed grips ( 34, 35 ) for thumb and fingertips to securely grip and turn the handle ( 30 ) with the required torque for actuating and de-actuating the disconnect switch.
