Glossary
■ Terms Related to Contacts
Carry Current
The value of the current which can be continuously applied to the
relay contacts without opening or closing them, and which allows the
relay to stay within the permissible temperature rise.
Maximum Switching Current
A current which serves as a reference in determining the perfor-
mance of the relay contacts. This value will never exceed the current
flow. When using a relay, do not exceed this value.
Contact Form
OMRON uses the following relay terminology for the various polarity
and switch configurations.
1 FORM A: SPST-NO
1 FORM B: SPST-NC
1 FORM C: SPDT
2 FORM C: DPDT
Make-before-break (MBB) Contact
A contact arrangement in which part of the switching section is
shared between both an NO and NC contact. When the relay oper-
ates or releases, the contact that closes the circuit operates before
the contact that opens the circuit releases. Thus both contacts are
closed momentarily at the same time.

Technical Information
Contact Resistance
The total resistance of the conductor, as well as specific resistivities
such as of the armature and terminal, and the resistance of the con-
tacts. Contact resistance values given in this catalog are initial val-
ues. These values are not intended to indicate suitability or
unsuitability in actual use. The contact resistance values given are
measurement values for a stable contact circuit at a stable contact
resistance. This value is determined by measuring the voltage drop
across the contacts by applying test currents as shown in the table
below.
For most applications, use at least 1 A, 5 VDC for contact resistance
measurements.
Maximum Switching Capacity
The maximum value of the load capacity which can be switched with-
out problem. When using a relay, do not exceed this value.
For example, when maximum switching voltage V
