Middle terminal shall be the minus pole when using DC circuit.
Switch case is marked with (+) and (-).
Do not store near (5cm) highly magnetic items.
If actuation is interrupted when switching from ON to OFF, arcing
may continue and switch could be burned.
Inductive loads produce an arc caused by counter-electromotive force
when opening the circuit. Recommend inserting spark elimination cir-
cuit. Contact factory for details.
