Standard type integral hinged lever and roller actuators are available in choice of 2 mounting positions. Actuation lengths are dimensioned from centerline of switch mounting hole as shown below. Identifiers Switches with a "standard" operating force are identified by a Y next to the standard model description, e.g. D43Y. Switches with a "light" operating force are identified by an X next to the standard model description, e.g. D43X. Switches with 100,000 cycles approved per UL1054 are marked with L in circle. * Connector part #823-0518 (mates with Y5 only) ** Connector housing for RAST 5 QC terminals Drilling Patterns for PCB Terminals Mounting -- US Version Recommended mounting screw size: #4-40 Round head with washer.
