Terminology for switching parameters of electrical appliances for electronic appliances
Provided by HONYONE technology department
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.額定
額定是指一般以特定的條件為前提，表示開關(guān)特性、性能保證基準(zhǔn)的數(shù)值。例如，額定電壓、額定電流等。
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.電氣壽命
電氣壽命是指在觸點(diǎn)上連接額定負(fù)載，根據(jù)規(guī)定的條件進(jìn)行通斷時(shí)的壽命。
Electrical life
The service life when the rated load is connected to the contact and switching operations are performed.
3.機(jī)械壽命
機(jī)械壽命是指不在觸點(diǎn)上通電，按照規(guī)定的操作頻率使其動(dòng)作時(shí)的壽命。
Mechanical life
The service life when operated at a preset operating frequency without passing electricity through the contacts.
4.耐電壓
耐電壓是指在規(guī)定的測(cè)量部位施加1分鐘的高電壓，不會(huì)發(fā)生絕緣壞的極限值。
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.絕緣電阻
絕緣電阻是指與耐電壓相同的測(cè)量部位的電阻值。
Insulation resistance
This is the resistance value at the same place the dielectric strength is measured.
6.接觸電阻
接觸電阻是指觸點(diǎn)接觸部分的電氣電阻，一般表示包含彈簧和端子部分的導(dǎo)體電阻在內(nèi)的電阻值。
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（防震等級(jí)）
耐振性是指在使用開關(guān)的過程中，因受到振動(dòng)，閉路的觸點(diǎn)在超過規(guī)定時(shí)間不開離范圍內(nèi)的振動(dòng)。
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.耐沖擊性
耐沖擊性是指在使用開關(guān)的過程中因受到?jīng)_擊，閉路的觸點(diǎn)在超過規(guī)定時(shí)間不進(jìn)行開離的最大沖擊值。
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.允許通斷頻率
約許通斷頻率是指滿足機(jī)械壽命(或者電氣壽命)的最大操作頻率。
Allowable switching frequency
This is the maximum switching frequency required to reach the end of mechanical life (or electrical life).
10.溫度上升（溫升）
溫度上升是指在觸點(diǎn)上接通額定電流時(shí)，端子部發(fā)熱的溫度上升值的最大值。
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.操作度強(qiáng)度（操作力度）
操作強(qiáng)度是指在按鍵上朝操作方向施加規(guī)定時(shí)間的靜載重時(shí)，不會(huì)導(dǎo)致開關(guān)功能損壞的最大載重。
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.端子強(qiáng)度
端子強(qiáng)度是指在端子上施加規(guī)定時(shí)間的靜載重時(shí)（如無規(guī)定則朝所有方向），不會(huì)導(dǎo)致功能損壞（端子變形除外）的最大載重。
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).
