Relé DPDT,en

What is a DPDT relay? A DPDT relay is a relay has two separate switches that operate at the same time, each with one normally open contact or closed through a common entry. We can define the acronym as a DPDT relay two two-position switches.

DPDT refers only to contacts and relay switches, not being relative to its coil impedance, working voltage and current to your contacts.

Tipos-de-reles

Up an image that illustrates the most common types of relays, SPST, Relé SPDT, Relé DPST e Relé DPDT. And in the electronic scheme The above and B is input is the output.

SPST

SPST relay is the simplest of the relays because it has a simple key, it is widely used in electronic circuits that does not require a two-position switch. The SPST relay is commonly found at the contact of your NO switch (normally Open).

This release is mostly found in version Relay Reed, in other words, a relay having its reed switch, which is a key having a set of contacts inside a glass delivery tube with inert gas, to protect the contacts against atmospheric corrosion. The contacts are closed by a magnetic material or a small coil.

Relé SPDT

SPDT relay has only one key as the SPST relay but with two positions.

relay DPST

DPST relay is a relay with two switches, but with only one contact, which may be in (normally Open) or NC (Normally closed,pt).
