Panasonic EVPBDP0001–EVPBDP032 – Low‑profile Light Touch (Tactile) Switches for Compact HMI and Device Inputs

The EVPBDP0001–EVPBDP032 range belongs to Panasonic’s EVP-BD family of surface‑mount Light Touch switches. From my experience, these are picked when engineers need a reliable, compact momentary input on dense PCBs—think handheld testers, compact HMIs, small controllers, or front‑panel keys where you can’t spare extra height. You might notice that the “BD” footprint is a favorite in reflow builds because it balances crisp tactile feel with stable solder joints over long production runs.

Order Placement Process and Guarantees

• Warranty: 365 days from shipment
• Lead time: typically 1 week if in stock; no more than 1 month latest
• Payment: 50% advance; full balance before delivery
• Express options: FedEx, UPS, DHL
• Batch & traceability: reel/lot trace codes are provided on shipment labels

Key Features

• Low‑profile SMD design – Made for reflow assembly; helps reduce panel depth in compact control devices.
• Crisp tactile feedback – The dome structure delivers a clean click, improving operator feel on small HMIs.
• Momentary SPST‑NO – Standard normally‑open contact for straightforward keypad matrix or direct GPIO.
• Industrial‑friendly ratings – Typically up to 12 VDC / 50 mA, suitable for logic‑level inputs and debounced microcontroller pins.
• Multiple force/travel options – Suffix variants (0001–0032) commonly differ by actuation force, feel, or plating—useful for product line tuning.
• RoHS/REACH compliant construction – Halogen‑free options are common in this family for stricter compliance regimes.
• Pick‑and‑place ready – Supplied in tape‑and‑reel; stable seating helps reduce tombstoning in most reflow profiles.

Technical Specifications

Application Fields

• Compact industrial HMIs and controller keypads where board height is limited
• Handheld meters, portable testers, and small fixture controls in production lines
• Medical and lab devices (menu navigation keys, configuration buttons)
• Building devices, access control panels, and small automation nodes
• Consumer and white‑goods UI PCBs where click feel consistency matters

Advantages & Value

• Reliable sourcing – Broadly used Panasonic footprint; easier second‑sourcing within the EVP‑BD family in many cases.
• Assembly efficiency – SMD package shortens through‑hole operations; one customer told us it shaved ~12% off their keypad line time.
• Consistent tactile feel – Reduces field complaints tied to “mushy” keys on compact HMIs.
• Cost‑effective BOM – Stable pricing and reel packaging help optimize consumption across multi‑SKU builds.
• Design flexibility – 0001–0032 variants typically cover different forces and domes, so you can dial in click feel without PCB redesign.

Installation & Maintenance

• PCB & cabinet – Use standard FR‑4 with solder mask; ensure front‑panel openings don’t mechanically preload the switch. Provide adequate ventilation if the board carries other heat sources.
• Reflow guidance – Follow Panasonic’s recommended lead‑free profiles; avoid exceeding peak temps to protect the dome’s click characteristics.
• Handling – Place via vacuum nozzle; avoid side loads on the actuator. ESD handling is advised around associated logic ICs.
• Cleaning – If board washing is required, use approved solvents and avoid direct jetting at the actuator to keep flux/chemicals out of the mechanism.
• Routine checks – During service, confirm actuation force and electrical bounce meet your firmware debounce. Replace units showing degraded feel after high‑cycle use.
• Storage – Keep reels sealed and dry; typical shelf life is strong when stored at 5–30°C and <60% RH.

Quality & Certifications

• RoHS and REACH compliant materials for the EVP‑BD family
• Manufactured under ISO 9001 / ISO 14001 systems
• Manufacturer’s standard warranty supported by our 365‑day supply warranty

One thing I appreciate is how forgiving this series tends to be in mixed‑technology assemblies—if you run both reflow and a small wave step, the switches typically hold their feel over repeated pilot runs. If you want us to match a specific actuation force or travel across EVPBDP0001–EVPBDP032, share your target click force and we’ll identify the closest suffix codes.
