Dongguan Yinyin Hardware Products Co., Ltd. is a full-service enterprise that combines production, sales, and after-sales support. We welcome all buyers to contact us for detailed negotiations!
As a manufacturer specializing in professional silver contacts, in-mold riveting parts, stamping components, and low-voltage switches (such as wall switches and leakage protectors), we are dedicated to "safe electricity, safe switches, and safe electricians." Thank you for your attention and trust. Our goal is to provide the most comprehensive safety power solutions to our customers.
1. About Contacts
When dealing with frequent energization at 220V, the function of a contact is to reduce contact resistance, minimize arcing, and extend the life of the switch. Without proper contacts, it can be extremely dangerous. For example, in a 220V, 10A rated circuit, the contact should have a minimum diameter of 2.5 mm to ensure safe operation.
2. Arcs
Arcs are a familiar term, but many products, even from well-known brands, claim they can extinguish arcs. In reality, it's nearly impossible to completely eliminate arcs in standard switches. However, there are special types like thyristor switches used in industrial control systems. The common wall switches found in homes cannot achieve this. Even when two charged conductors make or break contact, an arc can occur at voltages as low as 12-20V and currents of 0.25-1A.
3. Contact Material
Many people don’t realize the importance of contact material, but toxicity is a concern. Most wall switches on the market today use silver-cadmium alloys, which contain cadmium — a highly toxic metal that can seriously affect the kidneys. This is why the ROHS directive was introduced. Europe has long banned such materials in electrical products, yet few consumers are aware of this.
4. Switch Structure
When buying a switch, people often focus on the feel, but the internal structure is actually the most important factor. Most switches sold in China use a bridge structure, similar to a seesaw, where sliding friction is used to perform the switching action. However, only less than 1% of the brands in China use a pendulum structure, which changes the friction type from sliding to axial or rolling, improving performance and durability.
5. Copper Sheet Thickness
Industry standards require copper sheets to be thicker than 0.6–0.7 mm to ensure reliability and conductivity.
6. Clearance
There must be a minimum clearance of 3 mm between terminals of different polarities, whether straight or spaced apart.
7. Wiring Screws
Copper screws are the best choice for reliable and durable connections.
