A wide variety of options
Relays are electromechanical switches that can be actuated by an electrical signal rather than by manually opening or closing the switch. This small signal acts as a gatekeeper for a much larger electrical signal. The ability to have low-power control over a high-power signal is what makes them such prominent electrical components. Selectech provides relays from leading brands such as Fujitsu Takamisawa, Omron, TTI (Tai Shing), Panasonic and more.
