Note:
The dimensions OP1 and OP2 apply to the D3D-211 only. The D3D-221
and D3D-231 are SPST-NC and SPST-NO respectively and so therefore
have only one corresponding dimension here (OP).
Precautions
Be sure to read the precautions and information common to all Snap Action and Detection Switches, contained in the Technical User’s Guide,
“Snap Action Switches, Technical Information” for correct use.
■
Correct Use
Mounting
This product does not have waterproof or drip-proof construction.
Ensure that water does not enter the switch interior. In particular, do
not use the switch in locations where water may be spilled or flow
over the switch. Doing so may result in deterioration of the insulation.
■
Cautions
Handling
Do not expose the switch to shocks, such as by dropping it. Doing so
may damage or deform the switch.
Do not apply lubrication to the sliding parts, such as pushbuttons or
actuators. Doing so may result in faulty operation or contact failure.
In order to ensure stable contact force for
NO
contacts, use an
operating stroke of at least 5 mm.
Wiring
Do not use the switch with a large force applied to the connector or
lead wire. Doing so may result in rattling or contact failure.
Storage Environment
Storing the switch in a plastic bag will help prevent discoloration due
to sulfuration of the (silver-plated) terminals.
Do not use the switch in locations subject to harmful gases or to high
temperatures or humidity levels. Depending on the location, it is rec-
ommended that switches be inspected between 3 and 6 months after
the date of manufacture.
Micro Loads
Even when using the switch within the operating range, if there are
inrush currents or surges, it may decrease the durability of the
switch. If necessary, insert a contact protection circuit.
Connectors
The terminals connect to JST’s HL Connector.
The HL Connector consists of the following components.
Contact: SSF-21T-P1.4
Housing: HLP-03V
Omron does not sell the HL Connector.
Contact J.S.T. Manufacturing Co. for these connectors.
