What is a "push on, push off" switch?

A push switch (button) is a non-latching switch that induces a brief change in the state of an electrical circuit only when physically pressed. A common type of push switch is the rocker switch, which changes states whenever it is rotated into one of its notches.

The term "rocker switch" comes from the fact that each pair of contacts can be set to either make or break the circuit. To do this, each contact needs its own notch on the switch blade. When the switch is in the "off" position, either no notch is aligned with the contact point, so no current flows through it, or the single notch aligned with both contacts opens the circuit. When the switch is turned to the "on" position, there are now two notches aligned with each contact, so current flows through both contacts at once.

This type of switch can control any device directly connected to it. For example, a light bulb can be plugged into a standard 110-volt household outlet and controlled by a rocker switch attached to that same outlet. The switch may have three notches, one for on, one for low, and one for off. If the rocker is turned all the way up, the whole circuit is activated; if any part of it is pushed down, that section of the circuit is closed.

How does a push-button switch work?

A push button switch is a compact, sealed device that, when pressed, completes an electric circuit. When turned on, a tiny metal spring within contacts two wires, enabling electricity to flow. When it is turned off, the spring retracts, contact is broken, and electricity does not flow. A push button switch is used for making electrical connections in situations where opening or closing the circuit many times is inconvenient or impossible. Examples include gas pumps at airports and rest stops along highways, and elevator call buttons in buildings.

The term "push button" originated with mechanical switches designed by Charles Franklin Bell and introduced in 1872. These were simple, flat devices with two plates separated by a small space. One plate had pins projecting from it; the other plate had holes shaped like the pins. You could press a pin into one of the holes to close the switch. The first push button was an improvement on this design, using a rubber diaphragm instead of fingers to touch the plates. This prevented dirt from getting onto the contact surfaces and kept out moisture too.

Electricity flows through any conductor (such as a copper wire) when there is a potential difference between its ends. The presence of a conductor prevents a spark from occurring when the terminals are pushed together. So long as enough pressure is applied to make solid electrical contact with both the actuating surface and the casing, a circuit will be completed and electricity will flow.

What type of component is a push button?

A push button switch is a device that regulates an operation in a machine or other form of process. They are used in the home and office, and are sometimes known as pushbutton switches or push switches. A switch may be single-pole double-throw (SPDT), having two positions: off and on; or it may be three-way, having one position for each choice available to the user. The three-way switch was introduced in 1938 by Honeywell on their Tradeline model train set.

Single-pole double-throw (SPDT) push buttons are used where only on or off conditions can occur. For example, this type of button is used to turn lights on or off. If you were to use three-way push buttons to control lighting, you could have one group turn off all the lights while another group turned them on again.

Three-way push buttons are used where three conditions must exist for the button to operate successfully. For example, this type of button is used to change channels on a television set. If you wanted to use it to turn off the light, you would need to remember to press the button twice instead of once like a single-pole double-throw button.

The term "push button" also refers to the mechanism itself, which operates based on physical pressure being applied to it.

What are push button switches used for?

Introduction The push button switch is a type of control switch appliance that is commonly used to turn on and off the control circuit. It is used in electrical automated control circuits to deliver control signals to contactors, relays, electromagnetic starters, and other devices. The term "push button" comes from the fact that these switches are activated by pressing a small metal dome or disk attached to each switch's casing.

There are two main types of push button switches: single-pole and double-pole. They are distinguished by how many terminals they have. Single-pole switches have one terminal and double-pole switches have two. Which type you need depends on what you want to do with the switch. Double-pole switches are easier to connect to another device because there are no current loops to worry about when making connections. Single-pole switches require careful consideration when connecting up wiring systems because if not done properly, the button will not work properly.

Single-pole switches are used where only one position needs to be able to shut off the power supply. This is usually the off position. Double-pole switches are needed if more than one position needs to shut off the power supply. For example, an automatic sprinkler system may have its own separate shutdown system so that if someone trips a break wire or otherwise interrupts the main line voltage, the system will not spray water.
