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.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.Electrical life
The service life when the rated load is connected to the contact and switching operations are performed.
3.Mechanical life
The service life when operated at a preset operating frequency without passing electricity through the contacts.
4.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.Insulation resistance
This is the resistance value at the same place the dielectric strength is measured.
6.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.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.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.Allowable switching frequency
This is the maximum switching frequency required to reach the end of mechanical life (or electrical life).
10.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.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.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).
