NO contacts
Normally open contacts (A pair of contacts which are normally open when no relay input is applied.)
NC contacts
Normally closed contacts (A pair of contacts which are normally closed when no relay input is applied.)
Transfer
contacts
Transfer contacts (NO and NC contacts that have a common contact terminal are collectively called "transfer contacts".)
The contacts shown in A and B are all transfer contacts. The NC contact is either on the right side or on the upper side.

A miniature motor which operates in synchronization with the power supply frequency.
Relay
An electromagnetic relay
LED
Used to indicate the operating status of the Timer.

[[Inrush Currents for Timers and Time Switches]]

"---" indicates a constant current and therefore the corresponding values are omitted from the table. All the values are approximate values and should therefore only be used as a guide.
