The main types of switches are as follows:

1 Classified by use: wave switch, band switch, recording and playback switch, power switch, pre-selection switch, limit switch, control switch, transfer switch, isolation switch, travel switch, wall switch, intelligent fire switch, etc.

2 According to the structure classification: micro switch, rocker switch, toggle switch, toggle switch, push button switch, key switch, as well as fashionable membrane switch, point switch.

3 Classification by contact type: The switch can be divided into three types: a-type contact, b-type contact and c-type contact according to the contact type. The contact type refers to the relationship between the operation status and the contact state of “the contact is closed after the switch is operated (pressed)”. It is necessary to select a switch with an appropriate contact type according to the application.

4 Classification according to the number of switches: single-control switch, double-control switch, multi-control switch, dimmer switch, speed control switch, splash-proof box, doorbell switch, induction switch, touch switch, remote control switch, smart switch, card access switch , Yuba special switch.

The main parameters:

1 Rated voltage: refers to the safe voltage allowed by the switch during normal operation. If the voltage applied to both ends of the switch is greater than this value, it will cause a spark breakdown between the two contacts.

2 Rated current: refers to the maximum safe current allowed to pass when the switch is turned on. When this value is exceeded, the contacts of the switch will be burned due to excessive current.

3 Insulation resistance: refers to the resistance value of the conductor part and the insulation part of the switch, and the insulation resistance value should be above 100MΩ.

4 Contact resistance: refers to the resistance value between each pair of contacts when the switch is on. Generally, it is required to be below 0.1-0.5Ω, and the smaller the value, the better.

5 Withstand voltage: refers to the highest voltage that the switch can withstand between the conductor and the ground.

6 Life: refers to the number of times the switch can be operated under normal working conditions. The general requirement is about 5000-35000 times.
