YAMAHA SMT 4.5×4.5 Tact Switch Nozzle
The component is a 4.5 × 4.5 mm SMD tactile push-button switch, and the black part is a dedicated/custom SMT suction nozzle designed to pick it up.
For Yamaha SMT equipment, I would not use a standard 301A/302A nozzle for this part. Yamaha documentation lists standard nozzles according to component geometry, while special-shaped components can require a custom nozzle.
custom Yamaha YS12/YS24 nozzles have been made specifically for push-button tact switches, including a Yamaha 301A-base custom nozzle.
Machine: Yamaha SMT / YS-series style
Component: 4.5 × 4.5 mm tactile push-button switch
Nozzle type: Custom / special nozzle for tact switch
Purpose: Pick the switch from the feeder and place it onto the PCB
Black tip: Appears to have a recessed/formed vacuum pickup surface, rather than a conventional small round nozzle opening
Likely reason: The raised center button and four corner features make a normal flat suction nozzle unsuitable.
The 4.5 × 4.5 mm switch size shown in your photos is also consistent with commercially available SMD tact switches of this form factor.
Important: I cannot reliably determine the exact Yamaha part number from these photos alone. The nozzle looks like a special/custom nozzle, rather than one of Yamaha’s normal 301A–307A standard tips.

This is a non-standard custom-made contour nozzle**, specifically designed for SMT pick-and-place machines to pick up **4.5×4.5mm push-button tact switches**. It is compatible with Yamaha YV/YS/YSM series pick-and-place machines and is a dedicated nozzle for irregularly shaped materials. There is no original standard model; all are custom-made parts.
Material: 4.5×4.5mm four-pin push-button tactile switch (square component in the picture); the nozzle uses a **sleeve-in structure**, which covers the button plunger of the switch, not the component body. This solves the problems of ordinary nozzles such as misalignment, component rejection, and vacuum leakage when picking up components through the central through-hole.
Key Parameters (Industry-Common Custom Specifications)

Item | Parameter |
| — | — |
| Compatible Components | 4.5×4.5 mm SMD tact push-button switch |
| Nozzle Inner Hole | φ2.6-2.7 mm (for matching button post outer diameter) |
| Suction Method | Insert button plunger (suction of button head) |
| Compatible Models | YV100XG/YV100II; YS12/YS24; YSM10/YSM20/YSM40R |
| Material | Alloy, black hard anodized |
| Features | Anti-rotation, anti-throwing, avoids the switch center through hole, stable airtightness |
### Common Pain Points (Why Use a Dedicated Nozzle?)
1. Standard nozzles suck up component bodies: The switch has a cavity in the middle, causing vacuum leakage and identifying throw-out components;
2. Directly suctioning the top surface of the button: prone to slippage, component rotation, and placement misalignment;
3. **This nozzle is a sleeve type. The button post is inserted into the nozzle, and vacuum is applied from the side wall to firmly lock the material in place, preventing rotation and misalignment.
