A switch manufacturer tells you what a push button switch is? Push button switches have advantages such as low contact resistance, precise operating force tolerance, and diversified specifications. They are widely used in electronic devices and white goods, such as audio-visual products, digital products, remote controls, communication products, household appliances, security products, toys, computer products, fitness equipment, medical equipment, counterfeit bill detectors, laser pen buttons, and so on.

      Because of the environmental conditions of push button switches (applied pressure less than 2 times the spring force / ambient temperature and humidity conditions, and electrical performance), large equipment and high-load buttons use conductive rubber or metal dome switch hardware shrapnel as a direct replacement, such as medical equipment and TV remote controls.

      Regarding the pin configuration of the five-pin push button switch: two pins form one group. When correct pressure is applied to the switch body, the four pins conduct with each other, and the fifth pin serves as the grounding function.

      Push button switches are the fourth-generation switch products developed in response to the requirements of electronic technology development. The early sizes were 12mm*12mm and 8mm*8mm, and now they are 6mm*6mm. The product structures include vertical, horizontal, and horizontal with ground terminal types. Now there are also combined types (3M, 4M, SM, 6M, SM) and potentiometer push button switch combinations, meeting the requirements of various domestic electronic products. The mounting sizes are 6.5mm*4.5mm, 5.5mm*4mm, and 6mm*4mm. Overseas, there are already 4.5mm*4.5mm small push button switches and chip-type push button switches, with the chip type suitable for surface mounting.

      Now there is already the fifth-generation switch—the membrane switch, which has the same function as the push button switch and is mainly used in electronic instruments and CNC machine tools, but it has high resistance and poor tactile feel. To overcome the poor tactile feel, some membrane switches do not use a silver layer as the contact point but instead install a contact spring leaf inside.

      Push button switches are divided into two major categories: those using metal spring leaves as the switch contact pieces are called push button switches, which have low contact resistance, good tactile feel, and a crisp "click" sound. Those using conductive rubber as the contact path are commonly called conductive rubber switches. These switches have a good tactile feel, but high contact resistance, generally between 100 and 300 ohms. The structure of a push button switch relies on the button moving downward to make the contact spring leaf or conductive rubber block touch the solder tab, forming a circuit.
