This specific version features a standard 6x6mm square base with an ultra-low 4.3mm height (measured from the bottom of the base to the top of the flat actuator). This low-profile design makes it perfect for tight project enclosures, custom keypads, and surface-level PCB mounting.\u003c\/p\u003e\n\u003cp\u003eAvailable at Tomson Electronics, this 4-pin switch is engineered with an industry-standard 2.54mm pitch, ensuring it is fully compatible with solderless breadboards and standard through-hole perfboards. It operates as a normally open (NO) single-pole, single-throw (SPST) switch. The circuit remains open until the button is firmly pressed, delivering a distinct, satisfying mechanical \"click\" to confirm user input.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePeople also search for:\u003c\/strong\u003e 6x6x4.3 switch, tactile button 4.3mm, low profile push button, momentary micro switch, breadboard button, smd button replacement.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Tactile Push Button (Momentary)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 6mm (Length) x 6mm (Width) x 4.3mm (Height)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuit Type:\u003c\/strong\u003e SPST-NO (Single Pole, Single Throw - Normally Open)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Count:\u003c\/strong\u003e 4 Pins (Through-hole)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent\/Voltage Rating:\u003c\/strong\u003e 50mA \/ 12V DC (Typical)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Resistance:\u003c\/strong\u003e ≤ 50mΩ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLife Expectancy:\u003c\/strong\u003e ~100,000 cycles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eApplications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMicrocontroller Inputs:\u003c\/strong\u003e Perfect for creating digital input signals for user menus on Arduino, ESP32, and Raspberry Pi projects.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlim Electronics:\u003c\/strong\u003e Ideal for custom PCBs and 3D-printed enclosures where vertical space is highly restricted.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardware Reset:\u003c\/strong\u003e Wiring a dedicated, low-profile physical reset button to microcontroller boards or custom shields.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplacement Parts:\u003c\/strong\u003e Replacing worn-out or broken tactile switches in commercial appliances, remote controls, and toys.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eFrequently Asked Questions (FAQ)\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why does the switch have 4 pins if it only acts as a simple ON\/OFF connection?\u003c\/strong\u003e\u003cbr\u003eA: The four pins provide necessary mechanical stability when soldered to a PCB, preventing the button from snapping off during repeated presses. Internally, the pins are connected in pairs (typically, the two left pins are linked, and the two right pins are linked). Pressing the button bridges the connection between the left and right sides.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do I need a resistor to use this with my Arduino?\u003c\/strong\u003e\u003cbr\u003eA: Yes. If you connect this switch directly to a digital input pin without a resistor, the pin will \"float\" and read random noise when the button is unpressed. You must wire a physical pull-up or pull-down resistor (like a 10kΩ), or simply enable the internal pull-up resistor in your microcontroller's code (e.g., using \u003ccode\u003epinMode(pin, INPUT_PULLUP);\u003c\/code\u003e).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will this button stay pressed down after I push it?\u003c\/strong\u003e\u003cbr\u003eA: No, this is a \u003cem\u003emomentary\u003c\/em\u003e tactile switch. An internal metal dome spring immediately returns the button to its original un-pressed state the moment you remove your finger, breaking the electrical circuit.\u003c\/p\u003e\n\u003ch5\u003ePackage Includes\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e1 × Tactile Push Button Micro Switch (6x6x4.3mm)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TOMSON ELECTRONICS","offers":[{"title":"Default Title","offer_id":48359842906350,"sku":"Tactile Push Button Micro Switch 6x6x4.3mm | 4-Pin","price":3.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/MICRO_SWITCH_6X6X4.3_NO.488.jpg?v=1784620171","url":"https:\/\/www.tomsonelectronics.com\/products\/tactile-push-button-micro-switch-6x6x4-3mm","provider":"Tomson Electronics ","version":"1.0","type":"link"}
