Bryant 4821 SPDT 15A Momentary-Contact Pushbutton AC Switch
The Bryant 4821 is a single-pole double-throw (SPDT) 15A momentary-contact AC switch built for precise, repeatable manual control in commercial and industrial control-circuit applications. Rated for 15A of AC service, this momentary switch automatically returns to its neutral position once released, making it well suited for pushbutton-style control, signaling, and interlock circuits. As an SPDT device, the 4821 routes a single input to one of two output paths, supporting a wide range of control-circuit configurations. This switch is available in Brown, Ivory, and Light Almond finishes, so electricians can match device plates and interior finishes across a project while retaining the same SPDT, 15A momentary-contact performance.
