The 4A21BEA11 is a Series 4 pushbutton switch housing assembly. It features a black housing with protective barriers on the short sides and mounting clips on the long sides for secure, tool-less snap-in panel mounting. The assembly includes a 2-Pole, Double-Throw (DPDT) alternate action switching element equipped with 5-amp silver contacts and .110 quick-connect terminals. While it comes without a lamp, it has a socket to accommodate a T-3 1/4 wedge base lamp for illumination. This UL recognized and CSA certified switch is ideal for control panels requiring a modular design with convenient front-panel relamping.
