Push Button 4 Pin Tactile Switch

This 4-Pin Tactile Push Button Switch is one of the most fundamental components in hobbyist electronics, offering a simple normally-open connection that closes only while the button is actively pressed. That instant-make, instant-break behaviour makes it ideal for triggering actions rather than holding a state.

Commonly used to send signals to microcontroller pins on boards like Arduino, Raspberry Pi, or AVR, this switch can also power circuits directly or operate relays in larger designs. You will find tactile switches like this one everywhere from calculators and old-style keypad phones to PCB-mounted control panels and magnetic lock triggers, making it a genuinely essential part for any electronics project bin.

• 4-pin tactile switch – reliable normally-open connection
• Momentary action – closes only while pressed, no latching
• Microcontroller compatible – works with Arduino, Raspberry Pi, and AVR
• PCB mountable – easy to integrate into custom boards
• Versatile applications – calculators, keypads, control panels
• Can trigger relays – useful for larger switching circuits

Add reliable momentary control to your circuit with this Push Button 4 Pin Tactile Switch.
