Note: 1. Unless otherwise specified, all units are in millimeters and a tolerance of

±0.4 mm applies to all dimensions

2. The operating characteristics are for operation in the A direction (indicated by the arrow)

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.

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.

■ 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.

and D3D-231 are SPST-NC and SPST-NO respectively and so therefore

have only one corresponding dimension here (OP).
