Q = 1 (1, 0) – referred to as an S (dominated)-latch; Q = 0 (0, 1) – referred to as an R (dominated)-latch; This is done in nearly every programmable logic controller. Hold state (0, 0) – referred to as an E-latch; Alternatively, the restricted combination can be made to toggle the output. The result is the JK latch.
[1] [3] Hook-and-loop is regarded by some like Steven Vogel [5] or Werner Nachtigall [6] as a key example of inspiration from nature or the copying of nature's mechanisms (called bionics or biomimesis). Macro photograph of velcro hooks. The big breakthrough de Mestral made was to think about hook-and-eye closures on a greatly reduced scale ...
This dual threshold action is called hysteresis and implies that the Schmitt trigger possesses memory and can act as a bistable multivibrator (latch or flip-flop). There is a close relation between the two kinds of circuits: a Schmitt trigger can be converted into a latch and a latch can be converted into a Schmitt trigger.
I2C and I3C are also an example of master-slave technology. Modbus uses a master device to initiate connection requests to slave devices. An edge-triggered flip-flop can be created by arranging two gated latches in a master–slave configuration. It is so named because the master latch controls the slave latch's value and forces the slave latch ...
A latch bolt is an extremely common latch type, typically part of a lockset. It is a spring-loaded bolt with an angled edge. It is a spring-loaded bolt with an angled edge. [ 1 ] [ 2 ] When the door is pushed closed, the angled edge of the latch bolt engages with the lip of the strike plate; a spring allows the bolt to retract.
The typical shackle is a U-shaped loop of metal (round or square in cross-section) that encompasses what is being secured by the padlock (e.g., chain link or hasp). Generally, most padlock shackles either swing away (typical of older padlocks) or slide out of the padlock body when in the unlocked position.

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. Note: In this example, "Run" represents the status of a bit in the PLC, while "Motor" represents the actual output to the real-world relay that closes the motor's real-world circuit.
