Why get a Thermostat Switch with Gold Contacts?
One of the key advantages of gold snap disc contacts is their significantly lower contact resistance when compared to high-current silver contacts. This low resistance translates into improved electrical conductivity, allowing for smoother and more reliable signal transmission. This is especially important in applications where even the slightest interruption or distortion in the signal could lead to critical errors or malfunctions. Gold contacts should only be considered for applications with low voltage (>50 VAC) and low amperage (>1 amp). Gold contacts can be used with higher voltages and amperages, but they will not perform any better than silver contacts. In low current applications, silver may not be conductive enough for the switch to function reliably. Obviously, a switch that doesn’t function reliably will cause all sorts of problems with the system it’s connect to.
Another attribute of gold contacts is their compatibility with a wide range of materials. Whether paired with copper, aluminum, or other conductive materials, gold contacts maintain their exceptional conductivity and reliability, making them versatile and adaptable for various electronic setups.
The biggest plus to gold is that it has more resistance to oxidation and corrosion. Gold is highly corrosion-resistant, making it an ideal material choice for contacts in specific applications. This resistance to oxidation and tarnishing ensures that the contacts maintain their performance over an extended period, even in harsh environmental conditions. This longevity and reliability are crucial in applications where downtime or maintenance can be costly and disruptive. If your switch is in a harsh environment, you may also want to consider using an epoxy sealed switch. In addition to their technical benefits, gold contacts also have an aesthetic appeal. The gold plating adds a touch of elegance to electronic devices, which can be particularly important in consumer-facing products where appearance matters.
Gold contacts are a valuable choice for switches in applications using milliamp and millivolt signals. Their low contact resistance, corrosion resistance, material compatibility, and aesthetic appeal all contribute to their effectiveness in ensuring precise and reliable signal transmission. Choosing gold contacts can be a smart investment in achieving superior performance and durability in your electronic devices and systems.
