The Delfield 2194409 rocker switch provides electrical on/off control for compatible commercial foodservice equipment. Its double-pole, single-throw (DPST) design allows two electrical poles to be switched together, according to the connected circuit configuration. Measuring 7/8 inch by 1-1/2 inches, it offers useful dimensions for checking the control panel opening and mounting fit. Correct terminal arrangement and electrical ratings are essential when selecting a replacement.
