A108SYZQ04 is a single-pole double-throw (SPDT) toggle switch from the Gemini Series with silver contacts designed for reliable switching applications. The switch features a contact rating of 2 A @ 250 VAC or 5 A @ 125 VAC, with an insulation resistance of 1,000 Megohms minimum @ 500 VDC and dielectric strength of 1,000 Volts RMS at sea level. The switch incorporates a machined brass toggle with heavy nickel plating, a rigid one-piece die-cast copper-flashed frame, and epoxy-sealed terminals for environmental protection. It operates reliably across a temperature range of -20°C to +85°C with electrical life rated up to 30,000 cycles. This switch is ideal for industrial control panels, consumer appliances, and instrumentation where robust switching performance and long operational life are required.
