Relay SPDT Sealed

These are high-quality Single Pole - Double Throw (SPDT) sealed relays. You can use them to switch high voltage, and/or high current devices. Typical applications for this relay would include Power supplies, Air-conditioning, Monitor and Security alarm system, etc. But what can you make with it?

Solid State Relay

Theses solid-state relays (SSR) allow you to control high-current AC loads from a lower voltage DC control circuitry.

Solid-state relays have several advantages over mechanical relays. One such advantage is that they can be switched by a much lower voltage and at a much lower current than most mechanical relays. Also, because there are no moving contacts, solid-state relays can be switched much faster and for much longer periods without wearing out.
