Pushbutton Switches

Pushbutton switches are used for switching between multiple states (such as on, off, up and down) or for short-term user input, or for short-term electrical connections. The A22-TB-10A switch application field and working principle are outlined below in detail.

Application Field

The A22-TB-10A is a low-cost pushbutton switch designed for commercial and industrial applications. The main features of this model are its ruggedness and long-term reliability. Its base construction is of sturdy zinc-alloyed metal housing with a good elasticity spring and dielectric strength. The switch plate is made of reliable gold-plated contacts, which can bear moisture and be used in both dry and wet environments. The contact rated voltage of this model is up to 300V, with a contact resistance of less than 200 ohm. It also comes with a long service life of up to one million cycles and a 5 N operating force. Besides, it has an IP66/IP67 waterproof and dustproof rating, making it suitable for installation in areas with high dust or water spray.

Working Principle

When the button is pressed, it is connected to an internal circuit, which can be connected or disconnected to provide electrical power for the appliance. Each time the button is pressed, the switch conducts electricity, causing a current to flow. When the button is released, the switch breaks the circuit to cut off the power. This type of switch is known as a "momentary" switch, and it is used in many electrical and electronic devices. Another type of switch is a "latching" switch, which stays in either "on" or "off" position depending on how many times the button is pressed. The A22-TB-10A pushbutton switch is mainly a momentary type.

The pushbutton switch also comes with a number of pre-set specifications for each button. The user can set the total number of buttons, the number of buttons in a row, and the connection type between the swicth and the electrical device. For example, the user can specify whether the switch should connect to the device in series or parallel form. The switch also has adjustable delay settings, allowing the user to choose how long the power should be connected or disconnected when the button is pressed.

To sum it up, the A22-TB-10A pushbutton switch is designed for commercial and industrial applications, as it offers a complete set of features like high contact rated voltage, low contact resistance, long service life and durable construction. It also comes with customizable specifications for each button, including adjustable delay settings.
