Others
The load for the actuator (roller) of the Switch must be imposed on
the actuator in the horizontal direction, otherwise the actuator or the
rotating axis may be deformed or damaged.
When using a long lever model like the D4B-jj16N or
D4B-jj17N, the Switch may telegraph. To avoid telegraphing,
take the following precautions.
Correct Selection and Usage of Switches
Snap-action switch
A snap-action switch takes only a short time to switch electric cur-
rent, which reduces contact arcing and prevents contacts from wear
and tear. Therefore, a snap-action switch is more ideal than a slow-
action switch for applications that require high repeat accuracy, high
operation frequency, and slow operating speed.
Slow-action Switch
The electric current switching time of a slow-action switch differs in
proportion to the operating speed of the switch. A slow-action switch
operates safely via direct drive positive contact opening even after
metal deposition between mating contacts and provides insulation
capability after contact separation. Opposite polarity ensures high
contact reliability, even when voltages and currents are small and
allows switching of voltages of different potential by contacts blocks
with several contacts. For example, it is possible to perform a con-
trol function with 220 VAC and signalling function with 60 VDC using
only one device.
Safety Switch
The NC contact section of the D4B-jN’s built-in switch incorpo-
rates a shearing force contact separating mechanism. Therefore,
based on the above mentioned switching features, the snap-action
switch can be mainly applied to positioning control purposes and the
slow-action switch can be mainly applied to safety and protection
purposes. Both slow- and snap-action switches conform to
BS5304, IEC 204-1, and VDE 0113 safety standard.
