Rated current: refers to the maximum safety current allowed when the switch is switched on. When this value is exceeded, the contacts of the switch will be burnt out due to excessive current.
Insulation resistance: refers to the switch of the conductor parts and insulation resistance, insulation resistance should be in more than 100 m Ω.
Contact resistance: refers to the switch in the open state, between each pair of contact resistance. The general requirements under 0.1 0.5 Ω, this value is as small as possible.
Voltage: the maximum voltage the switch can withstand between the conductor and the ground.
Life span: refers to the number of times the switch can be operated under normal working conditions. The general requirement is about 5000- 35,000 times.
