MICROSWITCH MARQUARDT SERIES 1070-1075

Microswitches are switches for small/medium current, mainly used as components for electronic devices. Thery are used mainly into electronic devices, automated electrical machines and different other kinds of electrical applications.

For actuating a microswitch it need a very small force. Actual market gives you different choices for each specific final application.

The leader company of the sector is Marquardt Gmbh.

Founded in Germany in 1925, since the beginning Marquardt obtains great results putting their systems into industrial applications and, first of all, into automotive business. One of the products produced by Marquardt is, for instance, electronic keys for the most famous German automotive companies (e.g. Mercedes, Volkswagen and other top companies). Moreover, other main applications are power-tool modules for top brands of building market.

Between the main series of Marquardt switches, there are microswitches of series 1060-1065, mainly used in automotive business for “small signal current” (tens of mA), helpful for making connections between control unit and the other vehicle’s components.

Such kind of microswitches, differently by traditional snap-action ones, are characterized by sliding internal gold contacts. Thanks to sliding mechanism, they guarantee a bigger robustness and self-cleaning functionality.

Moreover, all these automotive switches have protection IP67 vs. dust and liquid fluids.

Series 1075, differently by series 1065 described in the past, is 3-state version, instead of traditional 2-state ON-OFF switches. Such new additional state has been obtained increasing insulating distance between ON-OFF states, reaching 0,85mm and obtaining a new Open-Circuit state.
In this way, final users will use a single microswitch, with 3 different functions, instead of 2 different devices as in the past. Finally, you will obtain advantages in terms of space and costs, which will the half.

Microswitches 1070-1072

Microswitches 1070-1072 with cable-harness are switches ON-Open Circuit-OFF with diagnostic version. Diagnostics, in such specific case, is guaranteed by two SMD resistors between terminals, with different calibrations for each specific case. Thanks to this functionality, central control unit is able to monitor, not only if current pass or not, but also its entity. In this way we’ll be able to understand if specific current is the desired one or, in opposite case, if there are damages in the system around our device.

Microswitches 1075-1078

Microswitches 1075-1078 are 3-state (ON/Open Circuit/OFF) version without diagnostic function. 

Their contact resistance is < 500 mΩ and insulating one is > 100 MΩ.

Actuator function of this specific series is guaranteed by a piston’s pressure and, for calibrating actuation forces and travelling distances, by different kind of levers (e.g. roller, simulatedroller ecc.). Moreover, actuation angle can reach
40° thanks to silicon material cover. Finally, terminals can vary for each specific case: available options are solder, pcb, faston and with cable harness.
