MSS4200RG is a 4PDT (4-pole double-throw) instrumentation grade slide switch from the MSS Series, featuring gold contact plating for reliable low-level signal switching. The switch offers an initial contact resistance of 20 milliohms maximum, insulation resistance of 1,000 megohms minimum, and dielectric strength of 500 VAC. It provides an actuation force range of 100 to 600 grams with a travel of 0.079" (2.01 mm) and a life expectancy of up to 15,000 cycles. The gold-plated contacts are rated at 0.4 VA maximum at 20 VDC or peak AC, making it ideal for precision instrumentation and test equipment applications where signal integrity is critical.
