Micro Switches Applications
Micro switches are widely used in many fields. In automated control systems, micro switches are commonly used to detect the position or motion status of an object to trigger the appropriate operation. They are also commonly used in buttons, switches and control panels in electronic equipment for switching and function selection of control circuits. In addition, micro switches are widely used in security systems, automotive electronics, home appliances, communication equipment and other fields.
A trigger that prevents the device from being disassembled
Devices such as infrared detection alarms, card readers, and access control panels will contain a nugget to trigger an alarm if the device is removed, disassembled, or damaged.
Micro Swithes Characteristics
Firstly, they are compact in size and suitable for scenarios where space is limited. Secondly, micro switches have high electrical and mechanical lifespan and can maintain stable performance over long periods of use. In addition, the trigger force and travel of micro switches can be adjusted according to specific needs to meet the requirements of different applications. Finally, microswitches are usually dustproof, waterproof and corrosion-resistant, enabling them to work reliably in harsh environments.
Elevator applications
Micro switches are used to manually open door switches and control panel switches for floor selection within elevators. In addition, the micro switches also serves to stop the elevator. When the elevatoris about to reach the designated floor, the sensing device makes a deceleration and stop command. The micro switches will disconnect the normally closed terminal, so that the elevator can stop at the designated floor normally.
Frequently Asked Question
Do you have any question?
A micro switch is a kind of pressure-driven fast switch, also known as a sensitive switch. The contact spacing of the micro switch is small, the action stroke is short, the press power is small, and the on-off is fast. The operating speed of the moving contacts is independent of the operating speed of the transmission element.
To know whether the micro switch is normal, you can judge the multimeter, unplug all the wires of the micro switch, or the insulation sleeve exit point, the multimeter hits the × 1K resistance file, measure the normally open, normally closed on-off, you can judge the quality of the switch.
