Unformatted text preview: ntrol switches, limit switches – Snap-action or slow make-and-break switches – Unenclosed position switches – Plastic-clad position switches – Metal-clad position switches – Safety position switches – Precision position switches The most important components of a mechanical micro limit switch are the contacts. The most widely used contact materials are: gold-nickel, fine gold, silver, silvercadmium oxide, silver-palladium and silver-nickel. By making an appropriate choice of contact material, it is possible to achieve favourable operating conditions in any field of operation of limit switches. By fitting actuators, limit switches can be used for a wide range of application possibilities. Typical types of such actuators are shown in the illustration. 26 © Festo Didactic GmbH & Co.
