Yellow Tommy MICRO LIMIT SWITCH WITH LONG HANDLE BUMP (Pack of 10)  (Black)

This is a simple momentary switch that is activated by pressing the handle. It is popularly used for object detection, proximity sensing, etc. It is a 3 Pin SPDT SwitchThese switches have a great 'clicky' sound to them with a nice tactile feel and are perfect when used for a slider, 3D printer, or robot project. Each microswitch is rated for 5A at 250VAC. You can connect a load that is to be turned on and off directly to the switch or connect the output to a microcontroller (Arduino/ESP32/Raspberry Pi) and read the switch status. This switch comes with a long handle, which is great when you want only a large displacement of the handle to trigger the switch. This miniature snap-action switch, also frequently known as a micro switch, is an electric switch that is actuated by very little physical force, through the use of a tipping-point mechanism, sometimes called an "over-center" mechanism. Switching happens reliably at specific and repeatable positions of the actuator. They are very common due to their low cost but high durability. The defining feature of micro switches is that a relatively small movement at the actuator button produces a relatively large movement at the electrical contacts, which occurs at high speed (regardless of the speed of actuation).
