what is the difference between a tact switch and a micro switch? the tact switch-like touch method is a click-and-click type, the connection is disconnected instantly, and the effect is relatively simple. it is generally suitable for single on-off (click-click connection and disconnection) of microelectronic products, while micro switches have multiple functions, which can be turned on and off to form a power circuit, or can be turned on normally, and can also be used as a power switch for detection. in other words, the micro switch can completely replace the tact switch, the most important thing is the cost.
the whole working process of the micro switch is: when there is no external force, the opening and closing isolating switch is in the same position, when the external force is released to make the transmission rod extend outward, the bow spring will deform, store mechanical energy, and cause deviation. when it reaches the ordered zero
when the boundary point is reached, the spring sheet is connected with the dynamic isolation switch, which produces an instantaneous jump, which leads to the connection, disconnection or conversion of the power supply circuit. after the external force is removed, the spring sheet will release the mechanical energy, resulting in the reverse deviation. when using another - a zero boundary point
, the isolating switch will be automatically corrected under the action of the spring sheet.
