Tamper 2 click contains a levered D2HW-A221D switch by Omron, which outputs signal in both positions - pressed and released. Omron switches, also known as microswitches, are well renowned for their reliability and endurance. The PCB of this click is designed so that the lever of the microswitch is easily accessible, making the click useful for all kinds of different applications, where precise, two position switches are required. Both the NO (Normally Open) and NC (Normally Closed) pins of the microswitch are routed to mikroBUS™, so it can be easily connected to the microcontroller. Switches of this kind are widely used in many different applications. The most common use of Tamper 2 click is door opening or closing detection, detecting the end of travel of a linear actuator, a Morse code input device and so on.
