Ohmite power Tap Switches (high power rotary switches) are constructed to provide dependable, convenient operation. All Ohmite tap switches, from 15 to 100 amps, have ceramic arc-proof bodies and metal alloy contacts. Their all-soldered and all-riveted construction assures mechanical and operational integrity. Even the smallest Ohmite Tap Switch, rated at 7 amps, has a reinforced non-metal body and solid metal alloy contacts. These units feature high current handling capability in a small package. FEATURES • “Slow-breaking, Quick-make” action proved best for switching AC current. • Non-shorting type disconnects previous circuit before establishing contact for succeeding tap. • Ceramic and metal construction provides resistance to arcing, burning and charring. • Tandem assemblies available as standard models. • UL listed for models 111, 212, 312 and 412 • RoHS compliant product available Jan. 2006 Add “E” suffix to part number to specify. Model 711: Using 3/8-32 bushing for 1/8” thick maximum panel. Four non-turn lug positions are possible on the single, unenclosed switch. Recesses in body of switch permit positioning of non-turn washer at “12, 3, 6 and 9 o’clock.” 3/16 “ hole for non-turn washer. Shaft 1/4” Model 111: For 1/4” panel, maximum, using 3/8-32 bushing and hex nut. A 3/16” hole is required for the non-turn washer. Shaft 1/4” Model 212: Using 3/8-32 threaded bushing and hex nut. A 5/32” hole is required for the non-turn pin. Shaft 1/4” Model 312: For 1/4” panel, maximum, use three 10-32 flat-head machine screws 3/8” long. Shaft 1/4” Model 412: For 1/4” panel, maximum, use three 10-32 flat-head machine screws 3/8” long. A 5/16” hole in panel is required for shaft. Model 608: For 1” panel, maximum, three flat-head machining screws 1/4-20, 11/4” long. Drill a 7/16” hole in panel for shaft. Shaft 3/8” NOTE: Since all tap switches are electro-mechanical devices, they are subject to wear and, therefore, have a finite life.
