  Push button set - Strong / Smart



Description

The combination of the cylindrical microswitch type AS1- and the push button actuator AK1-B* - creates a fully certified push button for use in hazardous area. The set can be installed directly as a device in Ex zone 1 or as a part of a control station in an Ex e or Ex t enclosure in zone 1 and 21. Two actuator elements are available according to local requirements. Due to its flat design and rounded edges, the Smart actuator offers little surface for external damage or dirt deposits. Because of its higher design, the Strong actuator enables the pushbutton to be used in housings with a depth of only 60 mm. The switches with changeover contact of type AS1- are available with cables in various lengths. The scope of delivery of a switch set includes: actuator, switch, black insert label, lock nut and protective sleeve.
