SWITCHES

A. SPIGOT SWITCH
The spigot switch is a normally closed, held open switch.
When a spigot is pulled, the spigot switch sends a signal
to the IntelliTec control to start the auger drive and refrig-
eration system. This signal moves the control to "Serve
Mode", or if it already is in "Serve Mode", it resets the
cycle count. After serving product, the IntelliTec continues
a freezing cycle until the product reaches consistency.
