Used to control circuit switching and triggering, this is a commonly used electronic component membrane key Switch. In the actual circuit design and assembly, the correct wiring method is very important to ensure the normal operation of the switch and the stability of the circuit. The following will introduce the membrane Keyboard connection method. Push-Button switches usually have four pins, two of which are in a group and the other two are in a group. One set of pins is used to connect the power supply and the other set of pins is used to connect the load or other circuits. The specific wiring methods are as follows:
Connect the power supply: Connect the positive terminal of the power supply to one set of pins of the switch and the negative terminal of the power supply to the other set of pins of the switch.
Connect the load: Connect the positive pole of the load or other circuit to a set of pins of the switch and connect the negative pole of the load or other circuit to another set of pins of the switch.
It is important to note that the pins of the film key switch are usually polarity free, that is, the two sets of pins can be interchangeably connected. However, in actual use, in order to ensure the reliability and stability of the circuit, it is recommended to connect the switch according to the above wiring method.
In addition, if multiple loads or circuits need to be controlled, multiple film key switches can be connected in series or parallel. The specific connection method needs to be determined according to the actual situation. You can refer to relevant circuit design manuals or consult professionals.
In short, the correct wiring method is the key to ensure the normal operation of the membrane switch and circuit stability.
