Mention of the switch we are very familiar with, indeed, our days wherever the use of electricity to the equipment or machines large and small there are built-in or external switch control, mentioned here is a member of the switch family with a pressure handle microswitch, this switch many people do not understand where to use, in fact, it is in many of our electronic products have played a very important role.
We touch the most used to pressure handle microswitch should be counted on the computer mouse, a small mouse so active and durable with this switch, in addition, there are some small appliances, communications equipment, automotive electronics, industrial machinery, power tools, medical equipment and many other categories are inseparable from the microswitch. Despite the small size with pressure handle microswitch, but there is such a big work, its operating principle is what?
Outside machinery through some transmission elements (press pin, button, lever, roller, etc.) to apply force to the action of the reed, and the accumulation of energy to the critical point, the occurrence of instantaneous action, this time the action of the reed end of the dynamic contacts and fixed contacts quickly connected or disconnected, as used for transmission elements on the disappearance of the force, the switch in the reed immediately occurred after the reaction force, which the circuit will be restored to the original, assuming that the transmission element The reverse stroke reaches the critical point of the reed's action, and the reverse action is completed in an instant.
Micro switch with pressure handle has its excellent function, there are some other switches do not have the characteristics, such as contact distance is small, press the power is small, and move a short stroke, on and off sensitive, which is also it is widely used elements.
