Omron D2F-5L Microswitch

Genuine Omron D2F-5L ultra-subminiature snap-action microswitch for endstop and probe builds that need a compact lever-actuated switch with a 5A contact rating.

Why this switch

• D2F-5L is the 5A, 250 VAC member of Omron's D2F basic-switch family with the L hinge lever actuator.
• Omron's D2F datasheet lists the series as an ultra-subminiature basic switch with split-spring snap action, insertion-molded terminals to resist flux penetration, and RoHS compliance.
• The Klicky Probe project specifically recommends an Omron D2F-5 or D2F-5L microswitch for the probe BOM; for D2F-5L use, remove the lever when the printed probe body expects the plunger style.

Specifications

• Manufacturer part number: Omron D2F-5L
• Switch type: ultra-subminiature snap-action basic switch / microswitch
• Contact form: SPDT, COM / NO / NC
• Actuator: hinge lever
• Terminals: PCB terminals, straight, through-hole style
• Rated load: 5A at 250 VAC per Omron D2F-5 family rating
• Contact material: silver alloy
• Minimum applicable load: 100 mA at 5 VDC

Intended use

Use it as a spare or replacement microswitch for printer endstops, CNC/automation limit sensing, or microswitch probe builds. For Voron-style magnetic probe projects, pair it with a Klicky Probe Kit or wire it with flexible 30AWG stranded FEP wire.

Gotchas

• This is the D2F-5L lever version, not the D2F-5 bare plunger version. Remove the lever only if your printed probe mount calls for it.
• This is not the low-current gold-contact D2F-01 family; Omron specifies a higher minimum applicable load for D2F/D2F-5 contacts.
• Confirm your mount and wiring before ordering; Omron D2F, D2HW, SS, and Z-series switches are not the same footprint.
