Metal Switch

 

Find Suppliers by Category

Switches are used to allow electric current to flow when closed. When opened, they prevent current flow. Common switch types include pushbutton, rocker, toggle, rotary coded DIP, rotary DIP, key lock, slide, snap action, and reed.

  • Switch Tips: Float-level switches
    field that the magnets generate actuates a magnetic reed switch mounted within the stem. The stem is a nonmagnetic metal or engineered plastic. The basic design provides an accuracy of about +-1/8 in. The float-on-stem configuration mounts in either the top or bottom of a tank. An alternative type
  • Switch Tips: Electro-Optic Level Switches
    for sensing fluid level at some distance from the top of a tank. Switch housings can be either plastic or metal alloy. Plastic housings tend to be Polyethersulfone or Isoplast, both of which handle temperatures above 200 F. Models made of Teflon work in corrosive liquids. Stainless or carbon-steel versions
  • Tips for metal-to-plastic conversions
    A switch to plastic may be one way of getting the leg up on the competition. No question a lot of metal parts have been converted to plastic over the past several years. But there are still many opportunities for conversion that go unevaluated. That's because designers sometimes dismiss plastics
  • Switch Tips: Reed switch basics
    A reed switch gets its name from the use of two or three thin metal pieces, called reeds, with plated contacts at their tips and spaced a small distance apart. The reeds are typically encapsulated in a sealed glass tube filled with inert gas. A field from a magnet or an electromagnet deflects
  • Plastic Vs. Metal in Piping Systems
    In many applications plastic pipe, valves and fittings can be a viable replacement for metal. Recent estimates show that about 25% of the expenditures for metal pipe, valves and fittings could be spent on plastic ones. And, in a lot of those systems, plastic would not just do the job, it would
  • Checking Cleaning Efficiency of Metal Parts
    For applications involving gas regulators, space shuttle components, weaponry parts or oxygen sensors, it is critical that metal parts must be free of hydrocarbon contamination before use. Prior to its ban due to ozone layer depletion, Freon was the most commonly-used solvent for metal parts
  • Switches and the NEC
    though local codes may be stricter. Article 404 spells out important provisions for grounding. There must be a means to ground a metal faceplate, even if the faceplate isn't metal. (Someone may install one later.) The Code considers a switch grounded to an effective ground-fault current path
  • Switch Tips: Membrane-switch basics
    feedback. The thicker the overlay, the less the tactile feedback. Membrane-switch overlays sometimes incorporate embossing to get a better look and add switch functions. There are two basic ways to emboss. The usual way is with metal-to-metal, male and female dies. There are height-of-emboss-area
