PK52 Push Button Now Also Available with Plastic Bezel

  • New Bezel offers larger variety and is more resistant to graffiti remover

The PK52 push button series impresses in the door area of buses and trains with its very good lateral recognition of the LED status display and its haptic button feedback. An optional acoustic orientation signal makes it easier for passengers to find the push button. On the PK52, the mounting screws are concealed by a bezel. Until now, TSL-ESCHA offered this bezel exclusively with powder-coated stainless steel. To meet the changing requirements, a bezel made of high-quality plastic material was designed. This means the operator can choose from a larger variety and, if desired, also replace the stainless steel bezel of the PK52 push button (from year of manufacture 2016) with one made of engineering plastic.

The PK52 has a high-quality appearance with the plastic bezel (here in black, RAL 9004).

The new PK52 bezel is made of a modern material that convinces with its high level of precision and accuracy of fit. The front panel is easy to mount. There is a noticeable click when attaching. The plastic front panel is not intended for multiple use but is a wear and spare part that can be easily replaced. Delivery times can be kept short due to high availability for spare parts.

The plastic bezel is currently available in eight common colors: traffic yellow (RAL 1023), traffic red (RAL 3020), traffic blue (RAL 5017), traffic green (RAL 6024), night blue (RAL 5022), light grey (RAL 7035), traffic white (RAL9016) and signal black (RAL 9004).

The high-quality plastic of the new front panel complies with the EN 45545-2 fire protection standard. Due to the material characteristics, the bezel is more resistant to graffiti removers and also more robust against cleaning chemicals. The new plastic bezel has successfully passed shock and vibration tests. Compared to the stainless steel front panel, the plastic bezel offers a weight saving of 24 grams.
