Rated voltage: refers to the safety voltage allowed by the switch when it is in normal operation. A voltage greater than this value is applied to both ends of the switch, causing a firing 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 contact of the switch will be burned due to excessive current.
Insulation resistance: refers to the resistance value of the conductor part and the insulation 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 in the open state of the switch. Generally, it is required to be below 0.1-0.5Ω, and the smaller this value, the better.
Withstand voltage: refers to the maximum 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 operating conditions. The general requirement is about 5000-35000 times.
