See further explanation on page A51. Processing Soldering: Manual Soldering for SIlver: ON-NONE-ON: See Profile B in Supplement section. ON-OFF-ON and (ON)-OFF-(ON): See Profile A in Supplement section. Manual Soldering for Gold, all circuits: See Profile A in Supplement section. Note: Lever must be in OFF (center) position while soldering. Distinctive Characteristics Inner o-ring and external rubber washer seal the switch to achieve IP68 of IEC60529 Standards (dust tight and water protected for temporary immersion). Waterproof boot at base of toggle further ensures protection against wet environments. Actuation provides smooth, sturdy tactile feel. Actual Size Polished, chrome-plated actuator paired with the waterproof boot not only delivers in terms of sleek design, but also functionality and reliability. Superb quality and construction design prohibit entry of harmful particles that may otherwise compromise lever operation.
