MANUAL PRESET INTERVAL TIMER WITH LATCH HOLDING MEANS FOR CONTACTS

摘要

Slow or incomplete closure of manual preset interval timer contacts during the setting operation is avoided by a latch which prevents closure of the contacts until the timer knob has been turned far enough to insure complete closure of the contacts. This latch allows the contacts to assume very close proximity before releasing. This closes the contacts with a positive and rapid movement and avoids contact bounce.
