Miniature recessed and limit switches
Miniature recessed and limit switches
Miniature built-in and limit switches from BARTEC GmbH are used in areas with limited space as a fire-resistant switching element. They are suitable for use in valves, thermostats, pushbuttons, actuators, level switches and switching mechanisms.
The smallest Ex d miniature switch is enclosed in a plastic housing. The bushings or cable shank are cast into the base. The standard version of BARTEC miniature switches contains fine silver contacts. Other contact materials such as, gold or gold plated silver are available for low currents and voltages.
The switches can be installed anywhere in devices and systems that provide mechanical protection. The connector cable is installed at the rear of the switch, the wires are colour coded. The (standard) cable length is 3 metres, other lengths are available on request.
