The knocker is the component that 'slams' when you win a free game on a pinball machine.
It is an essential element to your pincab that will make it more real than nature.
The Knocker is powered by a Freescale KLZ25 PCB and the Pinscape Config Tool app.
Knocker in standard exchange for all East and Sega Data Flipper.
This plate for Knocker is an extension of your Knocker.
When the Knocker is activated, its 'plunger' hits the metal plate, making a very striking dry sound.
