Actuators
Many special forms and lengths of actuators are available.
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 ʻYʼ next to the standard model description, e.g. D43Y.
Switches with a “light” operating force are identified by
an ʻXʼ next to the standard model description, e.g. D43X.
Switches with 100,000 cycles approved per UL1054 are
marked with ʻLʼ in circle.
