Pushbutton Switches

Pushbutton switches are an essential component of electrical control systems that allow operators to \'start\' and \'stop\' machines, turn systems on and off, or complete other operations. They come in a variety of forms, sizes and options to suit the application - from miniature switches to industrial, commercial and hazardous location products. The size and configuration of the switch components (and the environment of the fixture in which it will be placed) will determine the selection of the device.

The Pushbutton switch is a single pole device composed of two basic parts - a button and a contact. The contact is usually a snap-action device (like a relay) which allows electrical current to flow when the button is depressed, and automatically disconnects when the button is released. Often, the contacts are provided in normally open or normally closed configurations.

A Pushbutton switch typically has an actuator or button which the user presses, allowing an electric current to flow through the contacts. Commonly, this type of switch is used in applications where the user needs to manually operate the electrical system, such as to start and stop machines, lighting systems, fans, alarms and more. In addition, the Pushbutton switch is often combined with other components in order to create a functional control system, such as a timer, light switch, temperature regulator, circuit breaker, and more.

The Pushbutton switch operates in a variety of ways, depending on the type of switch being utilized. For instance, some switches use a mechanical lever or plunger that is pressed by the user. This type of mechanism is generally used in toggle switches, where the user presses the lever or plunger which causes the contacts to open or close. Other switches may utilize a pressure activated mechanism, where the user presses the button and the contacts are actuated.

In addition, some Pushbutton switches use a magnetic actuator which is activated by a magnetic field generated by a solenoid. These types of switches are commonly used to control electric motors, solenoids, pumps, and more. Finally, more advanced Pushbutton switches may include sensors that are integrated into the system, allowing for operation on command primarily based on the conditions of the environment.

The Pushbutton switch is an excellent choice for many applications in which manual control is desired. This is due to its simple operation, economical price, and rugged construction. Pushbutton switches are typically mounted in a variety of enclosures designed for hazardous locations, such as damp environments, and offer a higher level of protection than their conventional counterparts. Moreover, pushbutton switches come in various form factors and styles that allow for easy installation and maintenance.
