Although the micro switch is small, it has an irreplaceable effect in our daily life. It completes the automatic control system and safety maintenance in the machines and equipment that need to be frequently connected to the power supply circuit. At the present stage, it has been widely used in electronic products, instrument equipment, mining, power supply system, electrical products machinery and equipment, and its aerospace, aerospace, cruise missiles, heavy tanks and other defense industries. In addition, they can also be used in laptop mice, vehicle mice, vehicle electronics, communications equipment, military goods, And its test equipment, natural gas water heater, gas stove, small electrical appliances, microwave oven heating, rice cooker, pump pressure switch machinery and equipment supporting facilities, medical machinery, building intelligence, pneumatic tools and general electrical equipment and wireless communication machinery and equipment, 24 hours timer.

Microswitch operation steps

The operation procedure of the microswitch jeopardizes the characteristics of the power switch. The following points must be paid attention to during the actual operation.

1. Please use smooth looking power switch actual operation body (camshaft, baffle, etc.). The push rod of the power switch is rapidly acquired. When it is damaged, it is likely to cause the damage of the push rod and the reduction of its service life.

3. Please carry out the actual operation according to the posture and orientation of the push rod. In the fiber type, press the button vertically.

4. Steel ball swing rod and R-shaped swing rod, etc. Please carry out the actual operation from the position of the drawing below.

5. The Angle θ of camshaft and baffle of steel ball swing rod, etc., should be set within the range of 30 ~ 45°. If the Angle of view is too large, it will cause abnormal transverse ground stress to the swing rod.

6. Production and processing of the push rod will increase the external force effect of excess capacity on the internal organization of the power switch, resulting in the change of its characteristics and the failure of the power switch.

7. When the external swing rod is used as the actual operating body, in order to make a better decision based on the actual operating load of the power switch to add additional load, please determine the material, thickness, etc.

Common problems in microswitch applications

1) When fixing the acting body of the power switch, please use the small screw of M2 on the smooth surface to carry out fixing with the torque below 0.098N·m. In addition, in order to avoid loosening the screw, it is suggested to apply the sealing ring at the same time.

2) It must be noted that the posture body can not immediately increase the energy on the keys or the exciter under random circumstances, and the energy should be increased in the vertical direction for the keys when applied.

3) Posture setting after postures should be above 70 [%] of O.T. Under the condition of power switch, do not set the posture body in the posture degree part, in order to prevent impact with the opening and closing, over the travel arrangement to reduce the service life.
