SunRobotics Tactile Switch + Tactile Cap 12*12*7.3 MM Blue Colour 5 Pairs Electronic Components Electronic Hobby Kit

12x12x7.3 mm Tactile Push Button Switch & Cap is widely used as a standard input “buttons” on electronic projects. These work best when you mount it on PCB but can also be used on a solderless breadboard for temporary connections in prototypes. The pins are normally open (disconnected) and when the button is pressed they are momentarily closed and complete the circuit. This tactile switch also offers reliable dome contact technology and strong tactile feedback, with multiple operating forces to choose from. Applications include telecommunications, consumer electronics, audio/visual, medical devices, testing/instrumentation, and computer/peripherals. A “tactile switch” is one type of widely used switch that completes an electrical circuit typically when pressure is applied to the device by the user, which then gives the user a perceptible “click” or haptic bump in response, indicating current flow. Current flow is turned off when the switch is released. To give a shorter definition, a tactile switch is a momentary action device whose operation is perceptible by touch. This tangible feedback gives some assurance to the user that the switch has operated and a signal has flowed. Tactile switch models are also available that turn off current when the switch is pushed and turn it back on when released
