2017年11月24日 · Although forms A, B and C are by far the most common configurations. A “Form D” is similar to Form C as stated by @NewMC but differs from it by being a make-before-break instead of break-before-make. Essentially, Form D guarantees for a moment that all contacts are closed, while Form C guarantees for a moment all contacts are open.

2005年9月26日 · Re: Dry Form C Contact a "dry" contact is one that is a hard contact such as a relay or switch (as opposed to a triac or transistor). a form c contact is also called spdt. form a = no form b = nc form c = spdt form x = no with both terminals disconnected when off form y = nc with both terminals disconnected when off form z = spdt but without a ...

2017年3月2日 · As simple as switches are, how they are categorized can be difficult to understand. All switches have a certain number of poles and throws. This is expressed using this format: (Number of poles)P(Number of throws)T For example, SPDT is used to represent a Single Pole Double Throw. A pole can be thought of as how many common pins there are and a throw are the number positions that common pin ...
