Basic Micro Switch Types
Pin Plunger Spring
The pin plunger spring micro switch is one of the most commonly used types. It is designed with a simple pin plunger that is pushed down by an external force. When the force is removed, the plunger returns to its original position, making or breaking the connection within the switch. This type of micro switch is ideal for applications where a simple on-off action is required, such as limit switches in machinery.
Pin Plunger Spring Short
Similar to the pin plunger spring micro switch, the pin plunger spring short switch has a shorter plunger length. This type of micro switch is used in applications where space is limited and a shorter stroke is preferred. It offers the same reliable and fast operation as the pin plunger spring switch, but with a more compact design.
Hinge Roller Lever
The hinge roller lever micro switch features a lever arm with a roller at the end. When the roller comes into contact with an object, it pivots on the hinge, activating the switch. This type of micro switch is commonly used in applications where a larger actuation force is required or where the object being detected may have some movement or vibration.
Rotating Operation
The rotating operation micro switch is designed with a lever arm that can rotate up to 360 degrees. This allows the switch to be triggered from different angles or positions. It is often used in applications where the actuation force may vary or where rotational movement is required, such as door switches or joystick controls.
Standard Straight Levers
The standard straight lever micro switch features a straight lever arm that moves up and down. It is commonly used in applications where a simple up-down motion is required to activate the switch, such as elevator buttons or machine controls.
Long Straight Levers
The long straight lever micro switch has a longer lever arm than the standard straight lever switch. This allows for a larger actuation force or a longer stroke distance. It is often used in applications where a stronger force is required to activate the switch or where a longer lever arm is necessary for reaching the actuation point.
Extended Straight Levers
Similar to the long straight lever micro switch, the extended straight lever switch has an even longer lever arm. This provides an extended reach for applications where the actuation point is located further away or where a longer stroke distance is needed.
Small Simulated Roller Levers
The small simulated roller lever micro switch is designed with a lever arm that simulates the motion of a roller. It is ideal for applications where a smoother actuation is desired or where the object being detected has a curved or uneven surface contact.
Standard Simulated Roller Levers
The standard simulated roller lever micro switch is similar to the small simulated roller lever switch, but with a larger lever arm. It offers the same smooth actuation as the smaller version but with a higher actuation force capability.
Roller Levers
The roller lever micro switch features a lever arm with a built-in roller. When the roller comes into contact with an object, it rolls along the surface, activating the switch. This type of micro switch is commonly used in applications where a smooth and continuous actuation is required or where the object being detected has a curved or uneven surface.
L-Shaped Levers
The L-shaped lever micro switch is designed with a lever arm that forms an L shape. It is commonly used in applications where a different angle of actuation is required or where limited space prevents the use of a straight lever. The L-shaped lever allows for a flexible and customizable actuation angle.
How to Choose Micro Switch
The dimensions of a micro switch directly impact its current range, operating force, and stroke. Applications requiring a larger current typically need a larger switch. For example, in fuel tank applications, the micro switch used to detect the liquid level needs to provide a large stroke and withstand high currents. Conversely, smaller switches accommodate smaller strokes and currents.
Engineers need to know the rated voltage and current (DC or AC) required by the specific application to select the appropriate switch. Many modern electrical products emphasize low energy consumption, so the micro switch must function under low current (logic level load) and DC voltage. However, some applications, such as industrial pumps, require high current and high voltage.
Engineers must know the current and voltage ratings (AC or DC) required for a specific application to select the appropriate switch. As devices of all kinds in all industries strive for low power consumption, microswitches must be able to operate at low currents (logic level loads) and DC voltages.However, there are also applications that require switches capable of breaking high currents and voltages, such as industrial grade pump applications.
In addition to load requirements, engineers must also select the appropriate circuit. The switch contacts must be one of normally open (NO) and normally closed (NC). For NO type contacts, normally no current flows between the contacts. When the switch is actuated, the contacts are closed and the circuit is connected. For NC type contacts, current flows between the contacts normally. When the switch is actuated, the contacts are opened and the circuit is disconnected.
Switch reliability is critical. You need to determine how many electrical and mechanical operating life an application needs? Different switches have different contact materials, housings and terminals to meet the electrical and mechanical life requirements in different applications.
A highly reliable microswitch can operate 10 million to 20 million times before mechanical failure, and 50,000 to 100,000 times under maximum load before electrical failure.
As for the slight price difference between different quality switches, you need to take into account the total cost of use. Because you're not only paying for the switch, you're also paying for the long-term, trouble-free operation of the switch. In many cases, the additional cost of using a more reliable switch is offset by a lower warranty cost during use.
Environmental requirements have a great influence on the selection of microswitches, especially in applications requiring high reliability and criticality such as industrial control and medical equipment. Understand the environmental conditions of the application, including contaminants in the air that may enter the switch, the liquid in which the switch is located, and operating temperature requirements.
For applications in harsh environmental conditions, you need to choose a sealed switch with a wide operating temperature range. The highly reliable microswitches operate from -65 degrees Fahrenheit (-54 degrees Celsius) to 350 degrees Fahrenheit (177 degrees Celsius), making them easy to handle in a variety of applications. At the same time, it should also be noted that the protection level of the switch should be at least IP67 to prevent liquid intrusion. This eliminates the need to spend a lot of time designing an enclosure that achieves the same degree of protection.
Key certifications include UL certification in the United States, CUL certification or CSA certification in Canada, ENEC certification in Europe, and CQC certification in Europe. Ensuring the switch has the necessary certifications guarantees compliance with industry standards and enhances safety and reliability.
