1. What are miniature micro switches?

Miniature Snap-action switches (or micro switches since they're frequently called) are straightforward but innovative electrical switches that are found in almost all electrical appliances which range from residential to industrial functions. The interesting feature about them is that they require the use of hardly any physical force to switch. This happens because they make use of a"tipping-over" or"over-center mechanism", wherein the switch flicks into a suitable position automatically based on which side of the centerline it's crossed into.

2. Characteristics of micro switches

Micro Switches have a variety of qualities that make them immensely useful in various sectors requiring automation. Basically, their application is to be utilized in a control circuit. What it does, is that based on the information received and sensed from the switch through the management circuit, it finds changes in its surroundings, which act as stimuli for its own operation.

It makes use of two helical springs alongside an actuator because of its mechanism. This arrangement of 2 springs along with an actuator leads to its defining characteristic of a tactile click and sharp feel upon being changed.

This arrangement of the springs also allows for a small motion in the actuator to create a large movement in the electrical contacts through the use of the spring that further accelerates the movement already produced by the actuator.

3. However, why should you use micro switches?

Micro Switches are maybe the only thing following the human brain that could learn, adapt, and also be of use in any type of situation, here the situation being machines and circuit systems.

Mainly, they are of great usefulness in two situations- firstly, when there is only availability or suitability of low working force, but a definite action needs to be accomplished.

Secondly, and perhaps, above all, they serve their purpose where long term reliability is needed. Because their arrangement leads to the independence of the final force on the switch contacts from the operating force, this contact force, that will be always sufficient rather than too much, promotes lifetime.

4. Applications and uses

Micro Switches are used in a variety of electrical appliances, ranging from as small as a gas stove to as large as the convertible top of an automobile. The basic versions are employed in ice makers, ovens, electrical hot water heaters, etc. while there are watertight models used in lawnmowers and coffee machines.

In addition, there are automotive versions of micro switches. These automotive micro switches are heavily used in automotive intelligent control circuits.

Low-force models are used in vending machines which can sense the input of a coin in the machine. In cases like this, particularly the long-term lifestyle and reliability of the buttons comes in handy, as thousands of coins have been pushed into the vending machine throughout its working life.

Now That we've learned about the huge participation of micro switches in creating life simpler for us and making this world the awesome place that it's, you'd definitely be looking into getting your hands onto some of those micro switches to your business.
