Precautions
★Please
refer to "Common Precautions" for correct use.
Miniature Door Switch
Correct Use
●Mounting
This product does not have a waterproof or drip-proof
construction. Ensure that water does not enter the interior of the
Switch.
In particular, do not use the Switch in locations where water may
be spilt or flow over the Switch. Doing so may result in
deterioration of the insulation.
●Wiring
Do not use the Switch with Connector mounted and weight load
applied to the Connector and lead wire, otherwise it may rattle or
may result in connection failure.
●Using
Micro Loads
●Operating
Stroke
In order to ensure stable contact force for NO contacts, set the
total stroke at least 5 mm.
Even when using the Switch within the operating range, if there
3
D
are inrush currents or surges, it may decrease the durability of the
Switch. If necessary, insert a contact protection circuit.
