Pushbutton Switches

The A22-DA-01A is a standard pushbutton switch found in the industrial automation market. It is a single-pole, single-throw (SPST) switch which is operated mechanically with the push of a button. A common application for a single-throw switch is to operate a circuit when the switch is thrown. The switch can be used to help make an output signal to run a device or machine. The switch is also used in logic equipment, such as computers and programmable logic controllers (PLCs).

The A22-DA-01A switch is constructed from durable, waterproof material, making it suitable for both indoor and outdoor environments. The switch can be wired directly to line voltage, with up to AC 250V and DC 30V, and is designed to survive 40,000 operations. The switch is also designed to operate under temperatures ranging from -15°C to 85°C.

The A22-DA-01A pushbutton switch features an operating travel of 0.4mm, and an actuation force of 150gf. It has a function of a momentary action, meaning that the switch contacts are open when the button is not pressed and closed when it is pressed. The contacts on the switch are SPDT, meaning that when the switch is pressed, one of two contacts will be completed or opened, depending on the requirements of the device being controlled.

The switch is connected to the control board of the device, which allows the user to initiate the operation of the device by pressing the button. The control board then uses the signal from the switch to send a signal to the actuator, depending on the application, to either initiate or stop the device. In computer equipment, the switch is typically connected to the logic circuitry on the board, with the switch operating as a binary input.

In a typical application, the A22-DA-01A switch is connected to an LED indicator. When the switch is pressed and closed, the LED indicator turns on. This provides visual feedback to the user that the operation has been initiated. The switch can also be connected to other output devices, such as buzzers and horns, to provide additional feedback to the user.

The A22-DA-01A is an easy to use and reliable switch which is versatile and suitable for a wide range of applications. Its small size makes it suitable for cramped spaces and its design ensures that it will last for many years with minimal maintenance.
