[Term] EMI/RFI Shield [Definition] 
A special grounding technique that guards the switch from being affected by ambient Electro-Magnetic Interference (EMI), or Radio Frequency Interference (RFI). EMI or RFI may negatively affect circuit functions. These undesirable energy transients usually come through the wiring (conducted), or the shaft (radiated). Tests specified by MIL-S-3786 measure how these transients are shunted to ground.
