GENERAL INFORMATION
SPECIAL CIRCUITRY SWITCHES
‘‘Special sequence’’ switches provide un- provides a single pulse or momentary
usual circuit control. A make-before- closure of the contacts with each cycle of
break switch provides circuit continuity operation.
while switching from N.C. to N.O. In an-
other make-before-make switch, upon Double break versions can interrupt grea-
actuation, one circuit is made an interval ter inductive loads and feature shorting
before the second circuit. Another switch bar construction. A split contact version
allows control of the two isolated circuits.
Characteris tics : O.F. – Operating Force;
R.F. – Release Force; P.T. – Pretravel;
O.T. – Overtravel; D.T. – Differential Travel;
O.P. – Operating Position.
