Solution

a. A Push Button that instantenously removes power from a standard relay.

A pushbutton is a control device used to manually open and close a set of contacts. Pushbuttons are used in control circuits to perform various Pushbuttons functions.

For example, pushbuttons can be used when starting and stopping a motor. A typical pushbutton uses an operating plunger, a return spring, and one set of contacts. The following drawing illustrates a normally open (NO) pushbutton. Normally the contacts are open and no current flows through them. Depressing the button causes the contacts to close. When the button is released, the spring returns the plunger to the open position.
