Are you talking about using a gold contact? I'm a small relay for 24V. Do you need a gold contact?Let's talk about it.
No gold is necessary for contacts.1. The action of a contact on a pressure meter is equivalent to a switch used to conduct or disconnect the circuit. It does not require a power supply. The maximum operating voltage is 380V, and it can also be used for 220V or 24V (including AC and DC).2. Electric contact pressure gauge in the work process, will not contact in contact contact, due to voltage, spark will contact between the spark can burn contacts, lead oxide, so the electric contact pressure gauge work after a period of time will produce the phenomenon of bad contact, and can work normally after cleaning contact.3. In order to make the electrical contact work long time, it is important to note that the work power of the coil of the small relay in the back shall be controlled below 30W, otherwise it will burn up easily (contact power rating 30W).4. What material to choose contact is to consider comprehensively, choose pure gold or pure silver, only contact resistance is small, other aspects will not do.

Yes, the watch itself has a contact point. Don't you mean the table?
