Main Parameters Of The Switch

Rated voltage: refers to the safe voltage allowed by the switch during normal operation. If the voltage applied to both ends of the switch is greater than this value, it will cause a spark breakdown between the two contacts.

Rated current: refers to the maximum safe current allowed to pass when the switch is turned on. When this value is exceeded, the contacts of the switch will be burned due to excessive current.

Insulation resistance: refers to the resistance value of the conductor part and the insulating part of the switch, and the insulation resistance value should be above 100MΩ.

Contact resistance: refers to the resistance value between each pair of contacts when the switch is on. Generally, it is required to be below 0.1-0.5Ω, and the smaller the value, the better.

Withstand voltage: refers to the highest voltage that the switch can withstand between the conductor and the ground.

Life: refers to the number of times the switch can be operated under normal working conditions. The general requirement is about 5000-35000 times.
