Why is it worth to use a push-button with a declared resistance to dust and water even in a common environment?
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.

Toggle switches Marquardt 1820 series represent switches with a long-term proven switching mechanism and a high reliability.
Toggle switches have their stable place already for many decades thanks to their properties, especially an easy control even at tight assembly of more pieces next to each other. Moreover, the actuation characteristics of 1820 series is very fluent – smooth and very pleasant from the user point of view. With a mechanical endurance of 50 000 cycles they provide a really reliable solution.
of these switches is very simple – by means of an M12 metal nut. Directly from our stock we offer you types 1821.6101 (0-1 SPST), 1823.1101 (1-1 SPDT) and 1824.1101 (1-1 DPDT). In the Marquardt 1820 datasheet can be found detailed specification, as well as a list of available accessories.

If you´re searching for a rocker switch with small dimensions and a great design, then you shouldn´t overlook the Marquardt 1858.
Marquardt 1858 is a miniature 2-pole switch with 10A/250VAC rating, made of immediately self-extinguishing material (UL-94V0). Inspite of small dimensions it handles up to 100A inrush (capacitive) currents. Silver plated terminals provide a low resistance and a safe plugging of connectors (fastons) is ensured by double fixing of terminals in the switch housing. Ambient temperature on the terminals side can be up to 100°C, what enables to use the switch even in pent conditions of power applications. For an increased dust and water protection you can use the 203.089.011 transparent cover. The switch surface is silky matt with an abrasion-proof marking.
Small dimensions and an elegant design make the Marquardt 1858 switch suitable for applications like for example a main power switch of various devices, as well as for a control of peripherials. In the 1858 series there are available switches in various versions, in stock we keep 1858.1103 type. Detailed information will provide you the Marquardt 1858 datasheet as well as Marquardt switches overview.
