Omron Z-15GS-B Z Limit Switch
Couldn't load pickup availability
Omron Z-15GS-B Z-series basic switch for Voron-style Z endstop and general machine-limit duties. This is Omron’s Z-series slim spring plunger snap-action switch with screw terminals, SPDT contacts, and a 15 A resistive AC rating.
Why use this switch
- Slim spring plunger actuator: Omron lists Z-15GS-B in the Z-series slim spring plunger lineup, useful where a direct mechanical stop needs a compact plunger face.
- Screw-terminal body: the “-B” version is the screw-terminal model, so wiring is serviceable without soldering to the switch.
- Industrial Z-size switch: a larger, higher-current mechanical limit switch than small PCB microswitches, for builds that intentionally use this footprint.
Specifications
- Manufacturer part number: Omron Z-15GS-B
- Series: Omron Z general-purpose basic switch
- Actuator: slim spring plunger
- Contacts: SPDT / 1NO + 1NC snap-action
- Terminals: screw terminals
- Contact gap class: G, 0.5 mm

- Mounting: Omron specifies M4 screws with flat and spring washers for the Z body
Fitment and use
Use this where your Voron, CNC, or automation project specifically calls for an Omron Z-series plunger-style mechanical endstop. If you need a smaller probe or PCB-style microswitch instead, compare against the Omron D2F-5L Microswitch, Omron D2HW-C203MR, or Omron SS-5GL.
What it is not
- Not a Hall, optical, or inductive sensor; this is a mechanical snap-action switch.
- Not a generic mini endstop board; check your mount for the larger Omron Z-series body and plunger geometry.
- Not the hinge-lever version; this SKU is the slim spring plunger Z-15GS-B.

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
