A latching switch is a switch that maintains its state after being activated. [1] A push-to-make, push-to-break switch would therefore be a latching switch – each time you actuate it, whichever state the switch is left in will persist until the switch is actuated again. [2]
Push-to-break switch electronic symbol Push-to-make switch electronic symbol. A push switch (button) is a momentary or non-latching switch which causes a temporary change in the state of an electrical circuit only while the switch is physically actuated. An automatic mechanism (i.e. a spring) returns the switch to its
The most common type is a "push-to-make" (or normally-open or NO) switch, which makes contact when the button is pressed and breaks when the button is released. Each key of a computer keyboard, for example, is a normally-open "push-to-make" switch. A "push-to-break" (or normally-closed or NC) switch, on the other hand, breaks contact when the ...
A number strip would be peeled out and wrapped around the wire near the end. Wire numbers were made up of a series of the number strips so wire 1051 would be four strips. There are also pocket sized printers that print onto an adhesive backed label that can be wrapped around the wire. The basic format for relay logic diagrams is as follows: 1.
The key to understanding the latch is in recognizing that the "Start" switch is a momentary switch (once the user releases the button, the switch is open again). As soon as the "Run" solenoid engages, it closes the "Run" NO contact, which latches the solenoid on. The "Start" switch opening up then has no effect.

He pointed to Alabama’s 3-1 record against teams currently in the top 25, which was the best of that group. He also pointed to the fact that Alabama is 6-1 against teams above .500 while Miami ...
(from top) Single-pole reed switch, four-pole reed switch and single-pole reed relay. Scale in centimeters. A reed relay [i] is a type of relay that uses an electromagnet to control one or more reed switches. The contacts are of magnetic material and the electromagnet acts directly on them without requiring an armature to move them.
