SCHURTER Inc Swa1 120;240 Schurter 33.4503

The SWA1 voltage selector switch is a panel-mounted, two-stage series-parallel switch for selecting between two line voltages, with solder terminals and front-mounting compatibility. It supports panel thicknesses up to 8.5 mm and has an IP40 degree of protection. The device is rated for 6.3 A at 250 VAC across IEC, UL, and CSA standards, with an insulation resistance greater than 10,000 MΩ and dielectric strength exceeding 2 kVAC between line-neutral and 4 kVAC between line/neutral and protective earth. It operates from -40 °C to 85 °C and has a mechanical life of 300 cycles without load. The terminal contact resistance is less than 10 mΩ at 20 mV. The housing is made of black thermoplastic rated UL 94V-0 and weighs 3.9 g. The 120/240 V configuration is one variant within the series, identifiable by order number 0033.4503.
