A Mini Micro Switch, or trademarked as a toneluck switch, is a small electric switch that’s activated by very little manual force, via the application of a small tipping-point action, sometimes referred to as an over-center mechanism. The mechanical advantage of this over a regular switch is that the micro switch can be used in applications where a regular switch simply cannot be used, including applications that require precise, rapid response. For example, the toneluck switches are commonly used on medical laboratory equipment, military applications, aircraft controls, communications systems, and personal safety application applications. These switches also provide security in the form of magnetic pulls or pushes that prevent unauthorized entry. Also, these switches are used in many other situations beyond the aforementioned applications.
The term microswitch can be applied to both electrical and mechanical mini switches. Electrical mini switches are also referred to as pull-ups or push-ups. Micro switches that are comprised of a metal case that’s equipped with a permanent magnet or the like are known as solid state relays. When the switch is energized, it attracts a magnet which causes the switch to pull up or down.
An example of such a micro switch is the Se920 switch. The Se920 acts like a standard push-button switch but has a magnetic pull that goes counter-clockwise. When the user applies sufficient pressure to the pull-up mechanism, it causes a releasing motion that pulls up the outlet. The switch is positioned so that when it is released, the actuator’s gap engages a metal clip that prevents further re-activity of the magnetic attraction.
Mechanical mini switch (toneluck switches) have a similar advantage that electrical switches. They too need only a push button to activate or deactivate. However, they operate using a different mechanism than the electric variety. Instead of a pull-down mechanism, toneluck switches use a contact plate that has two metal slits separating it from the housing. When the user applies pressure to the switch using a wrench, the gap between the contact and the switch moves upward and engages a locking clip which holds the contact in place until released.
As with other switch devices, mechanical mini switch devices also feature two main types of plug: magnetic and non-magnetic. Magnetic types have a tendency to get stuck especially if care is not taken when plugging them in. This can result in damage to the electrical wiring. Non-magnetic types do not tend to get stuck unless care is taken. In fact, the opposite is true. A non-magnetic plug will tend to work more effectively and may even be able to detect a difference in magnetic field around it before getting stuck.
Mini switch devices are a good choice when one is looking for a very small but convenient switch. Compared to regular plugs, they are also easier to install and remove. This makes them an excellent choice if a simple installation is desired. They are available in a wide range of materials and may also be customized to suit specific purposes.
