ELECTRICAL:
The CS-501 is available with
a wide variety of snap-action switches. Contact arrangements include
SPDT, DPDT, and two-circuit double break. Almost all high-capacity
and special-purpose switches of the major switch manufacturers may
be specified. Also, more than one type of switch may be specified in
a multi-stack assembly. The switch supplied as standard (see switch
data below) is a general-purpose unit for handling the high inrush
currents of motors, solenoids and tungsten lamps.
ENVIRONMENTAL: The
actuating plunger of each switch is gasketed and the assembly is
highly dust resistant. Standard operating range is from -65°F. to
+180°F. Materials are corrosion resistant, and are of stainless
steel or aluminum alloy wherever practical. Models with switch cover
conform to NEMA Type I specifications. |

(NOTE: Model CS-501 Cam Switches are available in a variety of standard
and optional styles to provide choice of mounting, switch and adjustment
positions, as illustrated below. The drawings show physical
configurations, but are not intended to show the number of switches that
can be supplied in each style. For any style selected, the required number
of switches should be specified in accordance with the specifying
instructions below.)

How To Specify The complete specification
of a CS-501 Cam Switch to your requirements is provided by its part
number. This part number consists of six elements, arranged as follows:
Thus, in the example given here, the part number describes a side mounted
switch, with switches at 12 o'clock and adjustments at 3 o'clock; 12
switches in the assembly, using type T switches, with a 1/2" diameter
shaft and a 2.35" rear extension.
Modified Designs For Special Applications Special modifications and
adaptations of the CS-501 Cam Switch are available to meet particular
requirements. Typical variations include geared assemblies, units with
gear heads, special shafts, and special end bells. Precision Mechanisms
Corp. welcomes your inquiries and will be pleased to consult with you on
special requirements. |
