Standex Detect - Changeover Reed Switches
Reliable Break-Before-Make Switching with Form C Reed Technology
Changeover reed switches, also known as Form C or SPDT (Single Pole Double Throw) switches, feature three contact leads and operate with a break-before-make switching sequence. This means one contact disconnects before the other connects, ensuring clean signal transitions and reducing the risk of short circuits.
Changeover reed switches are ideal for applications requiring reliable switching between two circuits, such as signal routing, sensor feedback, and control logic.
These switches can be integrated into standard sensors and reed relay assemblies, and custom configurations are available to meet specific design requirements.

Magnetic Float NBR or Nitrile Butadiene Rubber floats have excellent resistance to petroleum-derived liquids such as oil and gasoline and can be used in high temperature applications as well. Magnetic Float PA or Polyamide floats are made of nylon, have a very high strength-to-weight ratio making them shock and abrasion resistant, enduring a pressure of 5 bar (73 PSI or 0.5 MPa). Magnetic Float PP (polypropylene) are rugged, highly resistant to many chemical solvents, bases and acids and have a water absorption of only 0.1%. V2A Floats are made of rust-proof stainless steel and are resistant to high temperatures making them ideal for the Food & Beverage industry among others.
