Are you working on sensitive applications like fire systems or elevators? Well, the first thing you need is an electrical control system. Second, you need micro switch types.
Contact us to discuss your requirements of Cheap Basic Plunger Model Micro Switch. Our experienced sales team can help you identify the options that best suit your needs.
Why do you need a micro switch? The tiny device is helpful for many applications that involve security, building, automation, etc.
We have micro slide switch types. And you need to understand how they work—to get the best one for your project.
Let’s dive in!
A microswitch is a minute snap-action device that requires little force to function.
What is a snap action switch device? It means when you touch the device with a particular stroke position, it switches instantly. And this happens without an operating force or hit operating speed. Further, you can rely on the micro safety switch for fast and efficient use.
In addition, this switch is usually NO (normally open) or NC (normally closed).
Typically, when the microswitch touches an object, the contacts change position. That said, the working principle of this switch includes:
When you depress or switch the actuator;
When you release the actuator, or it’s in a rest position;
Also, the micro-switches have vital features like the tipping-point mechanism. Interestingly, the feature helps to produce particular trip (operating) and reset (release) points where contacts will convert the state.
Here are other terminologies of the microswitch that will help you understand the working principle better:
Differential Travel
This term explains the space between the operating and release point. And the idea behind separating these two points is to guard the contacts against fast and unpleasant ON/OFF. And this happens when vibration tries to shorten your switch’s operating life.
Release or Reset Point
At this point, the switch contacts go back to their regular position.
Over-Travel
This safety feature is inside the microswitch. And it helps to stop damage to the switch. It does this by permitting the plunger to travel beyond its operating points.
Also, you have to ensure that the plunger doesn’t exceed its travel distance. Consequently, it will help to reduce damage and mechanical stress.
Trip Point or Operating
The trip point is the area where contacts change their initial state—which is an unoperated position.
The microswitch types include the following:
The flexible rod can rotate in any of the 3600 asides where it runs along the middle of the rod. Further, this switch has a small operating force. But it helps to indicate when there’s inconsistency in the shape or direction. Also, its plunger absorbs the overtravel. Consequently, it offers a large room in operation object play.
This switch usually has a roller that attaches to its hinged lever. And it’s ideal for high-speed cam operation.
Rotating operations are pretty familiar with low-torque actuators. Hence, this switch is best-suited for identifying light objects like paper currency.
Most manufacturers use steel for this lever. And the switch uses a reduced torque cam and speed. Plus, it allows you to alter the shape of the level to blend with the operating body.

Alignment is relatively easy with this switch. And it’s all thanks to its short plunger with a larger diameter. Also, overtravel is enormous.
With the leaf lever, you can generate a large stroke. All you need to do is bend in the lever. Further, you can use this switch for detecting various moving objects.
This lever is a simple roller type. And you can use this switch by bending in the leaf lever. While you’re at it, ensure that the end of the device turns into a curve.
The simulated lever is yet another simple roller type on this list. You can use it by bending the end of the hinged lever into a curve.
The pin plunger is ideal for short, direct stokes. So, you can use it directly to detect high-precision positions. Also, this switch needs a reliable stopper because its overtravel has the shortest actuator.
This microswitch has a more significant stroke. And it’s because of the powerful leaf spring. Hence, you can use it for cylinder drives or low-speed cams. Also, it’s vital to maintain the switch’s overtravel within an application’s specification for two significant reasons. First, to avoid damage. Second, it’s because the leaf spring has a fixed bearing point.
When you compare the spring pin plunger to a pin plunger, you’ll notice that it has a longer overtravel. However, you can also use this micro switch for the same applications. That said when you’re using this device, ensure the load is on the plunger’s center. And this is because the diameter of the plunger is slightly larger.
The difference between the leaf spring and this switch is that it comes with an attached roller. So, you can use it for cam,
You can operate this device with a cam. Also, it has a roller on its plunger. Even though the over travel is pretty tiny, you can adjust its position like the panel mount switch.
The hinged lever uses a low torque cam and speed. Plus, you can change the lever’s shape to balance the operating body.
When you compare this plunger to other types, it has the biggest overtravel. You can mount the switch to a panel with a hexagonal locknut and nut. Then, you can operate it mechanically or manually. Plus, you can use this device alongside a low-speed cam.
First, if you leave the circuit in the NC mode (unpressed lever), the LED light that links to the switch’s NC terminal glows. But if you impose a slight push on the lever terminal, the second LED light illuminates. And this happens because there’s contact between the common terminal (C) and NO terminals.
When you’re mounting side micro-switches, ensure you do it on a flat, smooth, and firm surface with the correct screw size. While you’re at it, don’t over-tighten the screws. Also, you can lock the microswitch with epoxy resin for added security.
There are different micro switch types. Some of them perform a similar function, while others do different things. So, the one you go for should depend on your project requirements. Also, it’s essential to mount your micro switches appropriately to get the best results.
