Q:What is Safety Standards?

Safety standards represent the minimum standards that are required from devices and components to prevent accidents and protect consumers who use electric devices from the hazards presented by electric shock and fire.

Q:What is Electrical Switch Durability (Life)?

This is the durability for operation at the specified frequency and stroke test conditions with a load connected and the rated current and voltage applied. When the contacts are switched, Contact Eroslon occurs.

Q:What is Mechanical Switch Durability (Life)?

This is the durability for operation at the specified frequency and stroke test conditions without supplying power to the switch. When the contacts are switched, Contact Wear occurs. Wear that occurs in contacts.

Q:What are switch Ratings?

The ratings are the values that warranty standards for the characteristics and performance of a switch. This generally indicates the maximum current that can flow through the contacts. The value of the current depends on the size of the voltage and the type of load.

Q:What are the two kinds of Resin Materials?

1. Thermosetting resin: These resins harden when heat is applied to them. They cannot be reused. 2. Thermoplastic resin: These resins melt when heat is applied to them. They can be reformed to recycle the materials.

Q:What are the two types of Manual Switch operations?

1. Momentary Operation: The switch is ON only while it is pressed. The switch turns OFF when it is released. 2. Alternate Operation: After you press the switch, the ON state is held even when the switch is released. To turn OFF the switch, you must press it again.

Q:What is the definition of a switch?

A switch responds to an external force to mechanically change an electric signal. Switches are used to turn electric circuits ON and OFF and to switch electric circuits.

Q:What does “Splashproof” mean?

Splashproof means the item can handle water splashes from any direction but should not be fully submerged like water-resistant devices.

Q:What does “Watertight” mean?

Watertight materials that fully prevent water from entering under specific conditions. This level of protection is stronger than water resistance. It not only keeps water out but can also handle higher water pressures, making it suitable for tough environments.

Q:What does “Water-resistant” mean?

This term broadly conveys that a product offers a degree of protection against water penetration, though not complete imperviousness. Water-resistant products are designed to withstand mild water exposure, such as light rain and splashes, without sustaining damage.

Q:What does “Waterproof” mean?

Waterproof materials are crafted to offer comprehensive protection against water intrusion, even when fully submerged. Products bearing the waterproof label have undergone rigorous testing to ensure they can withstand specific depths and pressures

Q:Doesn't gold work on silver contacts?

The contacts being discussed are internal to the switch, so the end user doesn’t have the ability to mix the two types. In general, it is best to use the same metals together instead of mixing them.
