Introduction to micro switches

Introduction to micro switches

A micro switch, as the name suggests, uses a switch with very small force. It is a switch that acts on the action reed by external mechanical force through the transmission element, so that the fixed contact at the end is quickly connected or disconnected from the moving contact.

Buttons for alerts and call points

The micro switch is used as a button in fire alarm, emergency stop control, emergency door release. These devices are designed to manually activate alerts by pressing them in an emergency.

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.

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.

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.
