How to judge the quality of the touch switch button
1. Good and bad measurement method: Use a multimeter to test the connectivity between the switch pins.Adjust the multimeter to the test resistance or conduction gear, and connect the two pins that control the switch state. If the multimeter displays a conductive state, it indicates that the switch is working properly;if it displays a non-conductive state, it indicates that the switch is damaged.
So here's how to use a multimeter to detect the quality of a tact switch: Tools required: multimeter;three-terminal microswitch First, prepare the required items.Turn on the power of the multimeter and set it to the on-off test position. If the multimeter displays 1, it indicates that the test pen is in the disconnected state.
First, disassemble the electric fan and locate the position of the touch switch button.Confirm whether the touch switch button is loose or damaged.If it is loose, it can be re-fixed.If it is damaged, a new touch switch button needs to be replaced.If there is no problem with the touch switch button, check for poor contact.
What is a four-legged button switch and how do you use it?
The four-legged tact switch is an electronic component commonly used for switch control in electronic devices.Here is a detailed introduction to the usage method and good and bad measurement methods: Usage method: Confirm the functions of the four pins of the switch.
A four-legged tactile switch (also known as a tactile switch) is a common electronic component used in key switches in electronic devices.Its working principle is to trigger electrical connections between metal contacts in a mechanical structure through the force of the human body, thereby transmitting signals in the circuit.
The general rule for conducting electricity is to have one foot on the left and one foot on the right. This can be tested using a multimeter to measure conductivity. The other two feet serve a fixing function.Two of the four feet are connected together, which means that in practical use they are the same as the two feet. This is for ease of installation, while the other two feet serve a fixing function.
Refers to an electronic component.In AD, a four-pin switch is called a "four-pin switch" or "four-pin button switch", which refers to an electronic component that is typically used to control the switching function in a circuit; this switch has four pins, two of which are used to connect to the power cord, and the other two are connected to the control device.
The connection method of the push-button switch with four pins: In general, the four pins are: a pair of normally closed contacts and a pair of normally open contacts.Using a multimeter: If the button is pressed down, the contacts are connected, and if the button is released, the contacts are disconnected, then this is a pair of normally open contacts, otherwise it is a pair of normally closed contacts.
The tact switch is to press once to connect the circuit, and the circuit remains connected after the hand is released. Pressing it again disconnects the circuit.The tact button is to press down to connect the circuit, and the circuit is disconnected when the hand is released.
