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
■ 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.
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 recommended 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.

Buyer's application or use of the Product. At Buyer's request, Seller will provide applicable third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself is not
sufficient for a complete determination of the suitability of the Product in combination with the end product, machine, system, or other application or use.
Buyer shall be solely responsible for determining appropriateness of the particular Product with respect to Buyer's application, product or system. Buyer
shall take application responsibility in all cases but the following is a nonexhaustive list of applications for which particular attention must be given:
(i) Outdoor use, uses involving potential chemical contamination or electrical
interference, or conditions or uses not described in this document.
(ii) Energy control systems, combustion systems, railroad systems, aviation
systems, medical equipment, amusement machines, vehicles, safety
equipment, and installations subject to separate industry or government
regulations.
(iii) Use in consumer products or any use in significant quantities.

changed at any time based on improvements and other reasons. It is our practice to change part numbers when published ratings or features are changed,
or when significant construction changes are made. However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers may be assigned to fix or establish key specifications for
your application. Please consult with your Seller representative at any time to
confirm actual specifications of purchased Product.
5. Errors and Omissions. The information in this publication has been carefully
checked and is believed to be accurate; however, no responsibility is assumed
for clerical, typographical or proofreading errors, or omissions.
