1. Rated current
- Maximum current that can be continuously flowed without deterioration of electrical and mechanical characteristics.
2. Rated voltage
- Voltage that can be applied continuously without deterioration of electrical and mechanical characteristics.
3. Contact resistance
- The electrical resistance of the contact bonded under specified conditions.
Normally, resistance (total resistance) generated by adding conductor resistance to contact resistance is often referred to as contact resistance, and stability is more important than resistance value.
4. Insulation resistance
- Resistance between insulated contacts.
5. Dielectric strength
- Limit value where dielectric breakdown does not occur when voltage is applied between insulated metal parts for 1 minute.
