Dynaswitch Field
Installation Procedures
To pick the proper sized Dynaswitch for the job, do the following:
1. Determine the mounting position.
2. Calculate the load to be applied to the Dynaswitch.
3. Refer to Table 1-1 to select a Dynaswitch with the proper capacity and
minimum/maximum set point range.
Loads applied to compression Dynaswitches cause the force beam legs to
deflect and come closer together. Loads applied to tension units cause the
force beam legs to deflect outward and spread apart. Microswitches are
S.P.D.T. and have three contact terminals. One is normally open, one
normally closed, and one is common. Therefore they can be wired to
make or break a circuit at specific set point(s).
To make a circuit:
1. on increasing compression load, use common and normally open
contacts.
2. on decreasing compression load, use common and normally closed
contacts.
To break a circuit:
1. on increasing compression load, use common and normally closed
contacts.
2. on decreasing compression load, use common and normally open
contacts.
To make a circuit:
1. on increasing tension load, use common and normally closed con-
tacts.
2. on decreasing tension load, use common and normally open con-
tacts.
To break a circuit:
1. on increasing tension load, use common and normally open contacts.
2. on decreasing tension load, use common and normally closed
contacts.

Dynaswitch
You can put together a test
assembly consisting of an
indicator light or horn, a power
source and two leads with
alligator clips to simulate the
machinery’s control circuit.
Any time the Dynaswitch is
removed from the machin-
ery and reinstalled, you
must check the switch
operation. Failure to do so
could result in inaccurate
actuation as the calibration
could change.
