General_technical_data Series Device General Environmental conditions Swisstac switches are modularly designed. They are divided in three groups: Shock resistance (single impacts, semi-sinusoidal) 500 m/s², puls width 11 ms, as per EN IEC 60068-2-27 max. 150 m/s², pulse width 11 ms, as per EN IEC 60068-2-29 1. Front Interface Human-Switch with state detector. 2. Intermediate section Set and reset device, lamp holder, latching funktion. 3. Switching element block Up to 5 switching elements can be integrated in a switching element block. Each switch is tested fully mounted. Electrical output and service life are determinated by the switching element. Front and inter­ mediate section are designed for maximum service life of the s ­ witching element. They determine in what way the switches are protected against external influences. The type approvals relate to the complete switch. Vibration resistance (sinusoidal) max. 100 m/s² at 10 Hz … 500 Hz, as per EN IEC 60068-2-6 Approvals Approbations CSA ENEC (EN 61058) UL VDE Declaration of conformity CE Front General The front notifies the switching status, serves for activation of the switch and determines its type of protection. With the exep­ tion of the front 18 mm dia. of the illuminated pushbuttons 55 and 70 mm, all front bezel elements have activation protection. Actuator 35 mm Polybutylene terephthalate (PBT), as per UL94 V0 Lock housing Polybutylene terephthalate (PBT), as per UL94 V0 Lock cylinder Polybutylenterephthalat reinforced with carbon fibre (PBT) sealing bulb IP 65 (Silicone) Environmental conditions Front bezel Polybutylene terephthalate (PBT), as per UL94 V0 EAO reserves the right to alter specific
