Latching Push Button Switches
Latching push button switches, also known as toggle switches or on/off switches, are a type of push button switch that maintain their state once they are activated. In other words, they have two stable positions, typically labelled as "on" and "off," and they remain in the selected position until manually toggled again.
Latching push button switches come in various configurations, including different sizes, styles, and mounting options, to suit different applications. Some switches may have additional positions, such as a centre "off" position between the "on" and "off" positions, providing more control options.
How do latching push button switches work?
- On Position: When the button is pressed or toggled to the "on" position, the switch completes the circuit, allowing electricity to flow. It latches into this position, maintaining the connection even when the button is released.
- Off Position: To turn off the switch, you press or toggle it again, causing it to move to the "off" position. This breaks the circuit, interrupting the flow of electricity. The switch remains in this position until it is manually toggled back to the "on" position.
Latching push button switches are commonly used in applications where it is desirable to maintain a specific state until intentionally changed. For example:
- Lighting Control: Latching switches can be used to control lights, allowing users to turn them on or off and keep them in that state until they decide to change it.
- Power Control: They are often used as power switches for devices or equipment where it is important to maintain the power state until explicitly turned off.
- Equipment Operation: Latching switches are utilised in machinery or equipment where a specific operation needs to be initiated or stopped, such as starting or stopping a motor, activating a pump, or engaging a mechanism
