The specifications of the switch selection are related to the parameters.

 

Before using the switch, we should pay special attention to some parameters and data, which are worth our attention. They mainly play the role of reasonable use, but also need to pay attention to the selection of specifications. The following is a detailed explanation of the content. I hope you can understand it carefully.

Toggle switch: A switch with a small contact interval and a fast-acting mechanism, which operates with a prescribed stroke and force and is covered by a shell, and has a driving rod outside.

Contact: In the switch type, compared with the semiconductor switch with switching characteristics, the mechanical switch of the contact is used to realize the function of the switch.

Contact form: Electrical input and output circuits of contacts are formed according to various uses.

Rating: Generally speaking, it refers to the value used as the reference to guarantee the switching characteristics and performance, such as rated current, rated voltage, etc. The premise is specific conditions.

Resin Fixation: After wire wiring is used at the terminal part, the part is fixed by filling resin, eliminating the exposed charged part to improve the anti-dripping method.

Insulation resistance: refers to the value of resistance between non-connected terminals, between terminals and non-charged metal parts, between terminals and ground.

Voltage withstanding: The critical value of insulation damage will not be caused by adding 1 minute high voltage to the specified measuring position.

Contact resistance: It represents the resistance of the contact part of the contact point, but generally represents the resistance value of the conductor resistance including the spring and terminal part.

Vibration resistance: When the vibration fretting switch is used by misoperation, the vibration of the closed contact points is not separated within the specified time.

Impulse resistance: Durable impact means that the micro-motion switch will not be damaged by the impact of the machine in transportation or installation, and meet the impact within the range of action characteristics. Misoperation impact refers to the impact range of the contact closed by the impact when the micro switch is used, which is not separated within a specified period of time.

Above is the detailed parameters of the switch, you can choose different specifications according to these parameters.
