What Is a Micro Switch?

Micro Switches are one of our product ranges here at Herga. They can be used for many different applications and are suitable for a range of industries.

What is a Micro
Switch?

 A Micro Switch is a
small, very sensitive switch which requires minimum compression to activate.
They are very common in home appliances and switch panels with small buttons.
They are typically inexpensive and have a long life meaning they can function
for a long time – sometimes up to ten million cycles.

Because they are
reliable and sensitive, micro switches are often used as a safety device. They
are used to prevent doors from closing if something or someone is in the way
and other applications similar.

 How does a Micro
Switch Work?

 Micro Switches have
an actuator which, when depressed, lifts a lever to move the contacts into the
required position. Micro switches
often
make a “clicking”
sound when pressed this informs the user of the actuation.

 Micro switches often contain fixing holes so
that they can be easily mounted and secured into place. Because they are such a
simple switch they require virtually no maintenance and they rarely need
replacing due to their long life.  

 Benefits of Using
Micro Switches

 As stated above, the
main advantage of using a micro switch is their inexpensiveness, along with
their long life and low maintenance. Micro Switches are also versatile. Some
micro switches offer a protection rating of IP67 which means they are resistant
to dust and water. This enables them to work in conditions which they are
exposed to dust and water and they will still function correctly.  

 Applications for
Micro Switches

 The Micro Switches we
can offer are commonly used in home appliance applications, building,
automation and security applications. For example:

  • Push
    buttons for alarms and call points
  • Turning
    devices on surveillance cameras
  • Triggers
    to alert if a device is dismounted
  • HVAC
    applications
  • Access
    control panels
  • Elevator
    buttons and door locks
  • Timer
    controls
  • Washing
    machine buttons, door locks and water level detection
  • Air
    conditioning units
  • Refrigerators
    – ice and water dispensers
  • Rice
    cookers and microwave ovens – door locks and buttons.

  

Herga uses micro switches in many
of our products including footswitches, pressure and vacuum switches as well as
hand controls.
