 Parallel connection
Since the leakage current of a 2-wire type switch increases according to the number of connected units, check
the input specifications of the programmable controller, which is a connected load, to determine the number of
switches to connect. For the 2-wire type switch, the indicator may become dim or not light up.
Although the leakage current of a 3-wire type switch increases according to the number of connected units,
the leakage current is very small (10 μA or less) and can generally be ignored. For the 3-wire type switch,
the indicator will light up without dimming.
 Switch for alternating magnetic field (T2YD)
When using the switch with a welding current exceeding 14000 A of alternating current, keep the
welding cable at least 35 mm away from the surface of the cylinder tube. (Test condition: Outside
diameter of cable is ø36)
Alternating magnetic field resistance (when the welding current is 14000 A of alternating current)
The switch for alternating magnetic field (T2YD) can be used if only one welding cable is in contact with the
cylinder or the switch. The welding cable must not be in contact with the cylinder or the switch if using two or
more welding cables or in a cable loop.
