DECA – SwitchLab Industrial Control Components

DECA push-in and screw connection terminal blocks

DECA is the brand of SwitchLab Inc., a Taiwanese manufacturer established in 1988 and headquartered in New Taipei City, with affiliated operations in Shanghai and Shenzhen. It designs and produces industrial control switches - 16mm and 22mm pushbuttons, push-in, limit, safety interlock, vandal-resistant metal and cam switches - alongside DIN-rail, barrier and PCB terminal blocks, I/O interface modules and, more recently, UQD liquid-cooling quick-disconnect connectors.

Controsys stocks DECA control units and interface terminals for panel builders and machine OEMs. See the full product range or the Controsys home page for our panel-building services.
