We can tell this switch is a normally-open (NO) switch because it is drawn in an open position. The lamp will energize only if someone presses theswitch, holding its normally-open contacts in the “closed” position. Normally-open switch contacts are sometimes referred to in the electrical ...

By selectively placing the bussing conductors and their associated stationary contacts in either the first or second pair of access apertures either a normally closed or a normally open electrical contact can be chosen. The contact module is attached to the outside of the housing by a mounting ...
Normally-open Contact This symbol typically represents the contacts of a relay, with power on both coming into the contact and power leaving contact. When shown on an output page, references are commonly shown to what drives the contacts. It can also be used as a digital input to a PLC. ...
The plane of the stationary contacts Fig. 3, lies at an angle to the plane of the integral terminals, so that in either position the terminals project through the same slots in the cover 21, Fig. 5, without having to use a different cover for each position. The stationary contacts 3, ...
Sometimes a relay can have contacts stamped with pin designations for one orientation and another set of pin designations for another orientation. For example, suppose that a relay has pin designations “A” and “B” for the contact in its Normally Open (N.O.) orientation. If you flip ...
known as pantographs, allow large electric contacts to move over larger distances and safely contact their counterparts. A proven reliable technology, pantographs are widely used in tramways and railway applications. Pantographs are separated into top-down and bottom-up systems depending on the mount...
You can have "clip-on" contacts for contactors. These are a part of the parent component and normally use the same tag. But you would ALSO want them in your BOM. If a child symbol has MFG/CAT attributes with values in it, it will appear in the BOM report. THL "JeffatICS" ...
