Application Case
Application of Micro switches in Production lines
Industrial control micro switches can be used in conveyor systems.
At the start and end points of a conveyor belt, these limit switches can detect whether materials are in place
and prevent materials from overflowing or piling up.
In addition, they can prevent motors or mechanisms from exceeding their design stroke, avoiding mechanical shock and equipment damage, and reducing downtime and malfunctions.
Application of Micro switches in Alarm System
In an alarm system, the push button switch primarily serves functions such as manual triggering, status confirmation, and system control. Its specific roles are as follows:
1. Manual Alarm Activation: In alarm systems, it is often used as a manual alarm button. When personnel discover an anomaly, pressing the button triggers an audible and visual alarm and initiates relevant emergency procedures.
2. Emergency Control: In some industrial equipment, the push-button switch is linked to the alarm or control circuit for emergency shutdown of equipment or to cut off dangerous actions.
Application of Micro Switches in DC Motor Control
In DC motor control systems, DPDT micro switches are commonly used in actuators for push rod motors, electric curtains, automatic doors, and valves.
This switch is typically used to change the polarity of the motor's power supply:
When the micro switch is in state A, the positive and negative terminals of the power supply are connected to the motor in one configuration, causing the motor to rotate forward;
When the micro switch is triggered and switched to state B, both terminals simultaneously reverse their connections, causing the motor to rotate in reverse.
This method allows for forward/reverse switching with a single mechanical trigger.
