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 ‘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.
