Profile: Multi Tech Industries Corp. offers a full line of custom rotary switches for communications and test equipment, ground fault analyzers and detectors, and Gripmaster strain reliefs. We have the capability to manufacture, assemble, and test, customer designed prototypes or components. Insulated Gripmaster is designed to provide terminal protection for all types of power cords for appliances, lighting fixtures, and instrumentation, where space is limited and high volume is required. It consists of a phenolic or fiber insulating material retained in a cold-rolled steel frame. We specialize in RF power applications. We also produce a line of instrument-grade electromechanical switches for commercial, industrial, military, institutional and OEM applications. Our rotary switches (open frame, enclosed frame), thumb wheel, key reader and other types are available to be integrated into the process controls or test instrumentation.
