Marquardt 5000 series push buttons won´t be scared of dust and water

In case, that a device is used outdoor, it is usually a necessity. But how is it in the case, that a device will be operated indoor in a relatively “good” environment? Here it depends mainly on a designer´s choice, whether he´ll use a component with a higher protection class or not. Despite the fact, that to use a push button with a higher IP class usually means somewhat higher price, but it provides one big advantage - reliability.
We know, that even in an indoor environment, especially in a production halls or stocks it´s very often a higher dustiness and a remarkably fluctuating humidity. These are naturally conditions, which don´t flourish to contacts, thus a button or a switch with a higher protection class can mean a significant increasing of reliability.

In the nowadays „microprocessor“ age, it´s very often, that the control buttons switch only a minimal current. As a result, this small current isn´t able to act as self-cleaning for contacts and the switches fail prematurely. Even in these cases, it´s beneficial, when a push button is more resistant to dust and water.

Marquardt 5000.0501 is a literally universal push button, because it features an IP54 protection class from both sides. It´s able to switch 4(2)A/250V AC and a plus is also a high mechanical lifetime - up to 200.000 cycles. Relatively higher driving force and a sufficiently long travel (4mm) acts also as a protection against accidental operation.
