753000-0036 is a part manufactured by C&K, a global manufacturer of electronic components. It is a tactile switch, which is a device used to register when a mechanical force is applied to it. This particular switch has momentary action, meaning that it will only close as long as the force is applied to it. It is a surface mount switch, meaning that it can be mounted directly onto a flat surface. It has a single pole, single throw (SPST) configuration, meaning that it will only allow the flow of current in one direction. It is a snap-action switch, meaning that it has a quick response time, and will snap back into its original position when the force is removed. It is rated for an operating force of 2.50 Newton, and has an electrical life of 100,000 cycles.
