Tactile switches are a tiny compact switches designed to mount into PCB boards, made to connect electronic components to form a circuit. Tact switches are an type of push button switch and electromechanical component for a PCB, as it was actuated by pressing. So it also called as PCB switch,they are mounted directly onto a PCB , surface mount PCB switches (SMD/SMT) lie flat on the PCB, tact switch was divided into surface mount and right angle as well as DIP type. Tact switches are also referred to as Tactile switches, referring to the slightly tactile function.
The LED light was inserted into the tact switch,so it has 6 pins ,there has red,blue,green,white,yellow,as well as bicolor LED options.
LED Tact switches have been used for a wide range of electronic devices for a wide range of applications from home appliance to medical equipment as well as Peripherals. Also used within the automotive industry, industrial controls, audio ,video and broadcasting industry, door entry and security. Tact switches are ideal for electronic devices and applications which have multiple out-put button functions.
