STATES Type SMH Test Switches combine over 60 years of experience in the design and manufacture of test switches with the latest improvements in material composition and construction techniques.
A complete line of switches is available for meter, relay, instrument, transducer and control system calibration, disconnection, troubleshooting, checkout and testing. All the features you need for any application — potential elements, current elements, make-before-break short-circuiting elements for current transformer circuits, test jacks are included.
Each switch blade can be operated independently or, where requirements dictate, adjacent handles can be ganged for simultaneous operation.
Features are incorporated for safety, durability, ruggedness and reliability. Where applicable, dimensions are in accordance with EEI-AEIC Meter and Service Committee Standards. All configurations are available in front-connected, back-connected or flush-mounted styles.
All switches can be provided in a back-connected version so that the switch is mounted on one side of a panel and the wiring connections are made on the opposite side. Backconnected switches have factory-installed insulated studs that project from the rear of the switch.
Flush-mounted switches consist of a standard back-connected test switch mounted in an insulated metal cabinet with cover. Flush-mounted switches match flush-mounted or semi-flushmounted relays, instruments, meters, etc., furnished on steel panelboards.
Rugged, virtually unbreakable covers for STATES Test Switches are available in clear or opaque styles. The covers are manufactured from tough, self-extinguishing, flame-retardant polycarbonate and are available for front- or back-connected versions.
The covers are constructed so that all switch blades must be closed when the cover is properly sealed. Switches provided with covers include two insulated, cadmium-plated steel cover studs that have holes for wire seals.
