Miba POWERcloser®

The Miba POWERcloser® is a fast-closing switch. For example, it is used for e-cars to ensure electrical safety in case of a crash, but it can also be used as a bypass switch for several industrial applications.

Pyro switch provides safety

The areas of application of the Miba POWERcloser® are multifaceted. Anywhere where two contacts have to be connected quickly and permanently, the pyro switch is the right product.

In the area of electromobility, it ensures electrical safety in case of a crash. In industrial applications, the POWERcloser® can quickly create a short circuit to bridge failed power units or simply support the tripping of other safety components.

How the Miba POWERcloser® works

Miba POWERcloser®: What are the advantages of the pyro switch?

The Miba POWERcloser® can short-circuit high currents. For a short time even 10 times the continuous current. Voltages of up to 1000 volts are no problem for the pyro switch. Depending on the design and application, the POWERcloser® can even be used hermetically sealed. Therefore, it is ideally suited for use in fuel cells in the hydrogen-circulated range.


In summary:

- Low resistance after closing

- Short closing time

- High locking capability for safe operation

- Flexibly adaptable to customer needs

Functionality is essential for a pyroswitch

The Miba POWERcloser® is a universal switch that connects two poles very quickly and safely. It is triggered by a small pulse. A pyro pill is used for this purpose. This principle has already been proven a million times over in airbags. This guarantees a very fast and safe closing of the two poles. It is no longer possible to open them afterward. Safe use is therefore guaranteed.
