Austrol heavy duty limit switches are engineered and manufactured in Australia to suit Australian conditions. The two models include:
- Hatchway Limit Switches (77HL)
- Track Limit Switches (77TL)
Austrol Type 77 limit switches feature a durable cast construction for proven reliability in adverse conditions. While the hatchway limit switches have cast aluminium construction, the track limit switches have cast iron construction. Austrol heavy duty limit switches are also weatherproof and dustproof to IP 54 requirements.
An oil impregnated bearing eliminates any need for lubrication while the iron operating lever is adjustable to any angular position. The contacts are manufactured in fine silver for improved reliability and reduced possibility of oxidation.
