Wiring
Warning
(1) Make sure to connect a load to the product before turning the power supply on. The switch will
damaged if no load is connected.
(2) Wiring should be kept as short as possible.
When the load which is operated by this product is an inductive load such as solenoid or relay, or
the lead wire is 5m or longer, use the contact protection box shown in the table below. Using the
switch without the contact protection box may cause breakage of the switch.
Internal circuit of the contact protection box
・
Connection to the contact protection box
For connection of the switch to the contact protection box, connect the lead wire indicating
SWITCH on the contact protection box and the lead wire from the switch. The lead length
between the switch body and the contact protection box should be less than 1 m, and set it as
close as possible.
Applicable lead wire dimensions are as follows.
Outer sheath: ø3.4
Insulator:
ø1.1
Conductor:
ø0.64
(3) Check the insulation of the wiring.
Avoid defective insulation (crossed lines with other circuit, ground fault, defective insulation
between terminals, etc.) with the wiring. If the insulation is defective, excessive current can flow
through the switch, which may cause damage to the switch.
