Meter Test Switches

The Eastern Specialty Company (TESCO)

TESCO introduced the original Meter Test Switch in the early 1920’s. Today, TESCO’s line of Test Switches has been redesigned with the intention to combine the best features of tried and proven switching methods with improvements in materials and construction. All of the current carrying parts are bright tin plated to prevent corrosion. Good operating contact is assured on periodic meter tests, even when the switch has been idle for long periods of time in an unfavorable atmosphere.
