Micro-switch: A switch with a micro-contact interval and a quick-acting mechanism, which operates with a specified stroke and force, and is covered with a housing and has a driving rod outside. (hereinafter referred to as a switch) has contacts: in the type of switch, compared with semiconductor switches with switching characteristics, the mechanical switch through the contacts to achieve the function of the switch. Contact form: electrical input and output circuit that makes contact points according to various purposes.
Rating: generally refers to the value as a guarantee of switching characteristics and performance benchmark, such as rated current, rated voltage, etc., its premise is a specific condition (type of load, current, voltage, frequency, etc.).
Resin fixation (plastic-encapsulated terminals): A method of improving drip resistance by filling resin to fix the terminal part after wiring with wires and eliminating exposed live parts.
Insulation resistance: refers to the value of resistance between non-connected terminals, between terminals and non-charged metal parts, between terminals and ground.
Voltage withstand: The critical value that the microswitch manufacturer will not cause insulation damage after adding 1 minute high voltage to the specified measuring position.
Contact resistance: Indicates the resistance of the contact part of the contact point, but generally represents the resistance value of the conductor including the spring and terminal part.
Vibration Resistance: When the misoperation vibration microswitch is in use, because the vibration closed contact does not separate the vibration range within the prescribed time.
Impact Resistance: Durable impact refers to the micro-motion switch in the transport or installation will not be damaged by the mechanical impact caused by various parts of the V and meet the impact within the scope of action characteristics.
Misoperation impact refers to the impact range of the contacts which are closed due to impact when the micro-switch is used, which is not separated within the prescribed time.
