Terminology for switching parameters of electrical appliances for electronic appliances

There are various definitions of electronic and electrical appliance switches in the electronic industry. Based on the practical experience in recent years, HONYONE makes a summary of common electronic switch grade parameters for customers, hoping to be helpful for customers\’ type ion and understanding of our company\’s finished drawings.

1.额定

额定是指一般以特定的条件为前提，表示开关特性、性能保证基准的数值。例如，额定电压、额定电流等。
Rated values
Values indicating the characteristics and performance guarantee standards of the switches.
The rated current and rated voltage, for instance, assume specific conditions.

2.电气寿命
电气寿命是指在触点上连接额定负载，根据规定的条件进行通断时的寿命。
Electrical life
The service life when the rated load is connected to the contact and switching operations are performed.

3.机械寿命
机械寿命是指不在触点上通电，按照规定的操作频率使其动作时的寿命。
Mechanical life
The service life when operated at a preset operating frequency without passing electricity through the contacts.

4.耐电压
耐电压是指在规定的测量部位施加1分钟的高电压，不会发生绝缘坏的极限值。
Dielectric strength
Threshold limit value that a high voltage can be applied to a predetermined measuring location for one minute without causing damage to the insulation.

5.绝缘电阻
绝缘电阻是指与耐电压相同的测量部位的电阻值。
Insulation resistance
This is the resistance value at the same place the dielectric strength is measured.

6.接触电阻
接触电阻是指触点接触部分的电气电阻，一般表示包含弹簧和端子部分的导体电阻在内的电阻值。
Contact resistance
This indicates the electrical resistance at the contact part.
Generally, this resistance includes the conductor resistance of the spring and terminal portions.

7.耐振性（防震等级）
耐振性是指在使用开关的过程中，因受到振动，闭路的触点在超过规定时间不开离范围内的振动。
Vibration resistance
Vibration range where a closed contact does not open for longer than a specified time due to vibrations during use of the snap-action switches

8.耐冲击性
耐冲击性是指在使用开关的过程中因受到冲击，闭路的触点在超过规定时间不进行开离的zui大冲击值。
Shock resistance
Max. shock value where a closed contact does not open for longer than a specified time due to shocks during use of the switches.

9.允许通断频率
约许通断频率是指满足机械寿命(或者电气寿命)的zui大操作频率。
Allowable switching frequency
This is the maximum switching frequency required to reach the end of mechanical life (or electrical life).

10.温度上升（温升）
温度上升是指在触点上接通额定电流时，端子部发热的温度上升值的zui大值。
Temperature rise value
This is the maximum temperature rise value that heats the terminal portion when the rated current is flowing through the contacts.

11.操作度强度（操作力度）
操作强度是指在按键上朝操作方向施加规定时间的静载重时，不会导致开关功能损坏的zui大载重。
Actuator strength
When applying a static load for a certain period on the actuator in the operation direction, this is the maximum load it can withstand before the switch loses functionality.

12.端子强度
端子强度是指在端子上施加规定时间的静载重时（如无规定则朝所有方向），不会导致功能损坏（端子变形除外）的zui大载重。
Terminal strength
When applying a static load for a certain period (in all directions if not stipulated) on a terminal, this is the maximum load it can withstand before the terminal loses functionality (except when the terminal is deformed).
