Operation
■ Single-side Stable Relays
The contacts of this simple type of relay momentarily turn ON and
OFF, depending on the energized state of the coil.
■ Dual Coil, Latching Relays
This latching relay has two coils: set and reset. It can retain the ON
or OFF states even when a pulsating voltage is supplied, or when the
voltage is removed.
Contact Styles
Contact ratings are generally indicated according to resistive loads
and inductive loads (cosφ = 0.4 or L/R = 7 ms). Contact shape and
material are also shown to guide the customer in selection of a
model suitable for the intended load and required service life.

■ Single Coil, Latching Relays
Unlike the dual coil latching relay, the single-winding latching relay
has only one coil. This coil, however, serves as both the set and reset
coils, depending on the polarity (direction) of current flow. When cur-
rent flows through the coil in the forward direction, it functions as a
set coil; when current flows through the coil in the reverse direction, it
functions as a reset coil.
■ Built-in Diode
A diode is built into some relays, wired in parallel with the coil to
absorb the counterelectromotive force (counter emf) generated by
the coil.
■ Built-in Operation Indicator
Some relays are provided with a light-emitting diode (LED), wired in
parallel with the coil. This permits a fast-check of the relay’s operat-
ing status.
When used at extremely low loads, the failure rate differs according
to the contact material and contact method, as shown in the figure.
For example, in comparing a single contact point with a bifurcated
contact point, the bifurcated contact model has higher parallel redun-
dancy and will therefore exhibit a lower failure rate.
