Design and operating principle
The command devices are fit for ∅ 22.5 mm mounting holes and suitable for spacings of 30 mm between centres. All command devices provide degree of protection IP 65/67 and are double insulated for class II.
The actuator is connected to the ES14 switch by a bayonet fastener. Available switching elements with slow action are: emergency-stop push buttons, push-buttons with and without diaphragm, selectors, control switches and key-operated switches.
All command devices shown in this chapter bear the CE mark according to the Low Voltage Directive 2014/35/EU and the emergency-stop push buttons according to the Machinery Directive 2006/42/EC.
