● About contact load

Select the appropriate switch rating for the contact load. If a current exceeding the contact load is applied to the contact, it will cause fusing and movement of the contact, which may result in a short circuit and burnout.

● About the type of load

Depending on the type of load, the constant current and inrush current as shown below may differ significantly. Select the appropriate rated switch according to the type of load. The higher the inrush current when the circuit is closed, the higher the consumption and movement of the contacts, which may cause fusing and movement of the contacts, and may result in short-circuit or burnout.

● About the operating environment

Do not use the switch in an environment with flammable or explosive gases. The arc generated during switching and the heat generated by the switch may cause fire or explosion.

● Shock to the switch body

Do not drop or disassemble the switch. Otherwise, the characteristics of the switch will not be satisfied, and it may be damaged, electrocuted, or burned.

● About durability (life)

The durability (life) of switches varies greatly depending on the switching conditions. Be sure to check the actual equipment under actual operating conditions and use it within the range of switching times permitted by its performance. If you continue to use the switch in a state of deterioration, it may eventually cause insulation defects, fused joints, poor contact, and damage or burns to the switch itself.
