Pinfall Switch
When a pin is knocked over, the pulling of the string causes the string roller and string gear on the Pin
Motion Interface to rotate. If the string pulls with enough force, a magnet attached to the string gear
through a friction clutch rotates to actuate a reed type switch. A pinfall sensitivity adjustment on the
Pin Motion Interface determines the amount of string pull force needed by controlling the distance the
magnet must rotate to actuate the switch.
The default factory setting is 10.
Refer to Figure 3-32.
