PB1973BBLKBLKEF0 application field and working principle

As a type of pushbutton switches, PB1973BBLKBLKEF0 is widely used in various occasions where reliable and high-quality products are required. PB1973BBLKBLKEF0 provides two or three contacts. The contacts are in the form of normally open (NO) or normally closed (NC) contacts with a U shaped contact element. The contact spacing is 40 mm, and the terminal size is 0.8 mm. PB1973BBLKBLKEF0 pushbutton switches are typically used as momentary controls that are suitable for either AC or DC circuits.

Working Principle

PB1973BBLKBLKEF0 is a type of pushbutton switches that uses a plunger to complete the action. When the plunger is pressed, a spring inside the switch is pushed against and compresses. This compresses the switch contacts and closes the circuit. When the button is released, the spring pushes the plunger, and the contacts will spring back out to open the circuit again. The spring is a tension spring that is pressed by the plunger and helps the switch to return to its unlocked position.

PB1973BBLKBLKEF0 pushbutton switches are considered as AC switches, since their current rating is based on their continuous operation at AC voltages. AC switches are usually wired to provide a direct current when the switch is switched on. A backup capacitor is typically used to provide the necessary DC voltage in case the AC power is lost.

Application field

PB1973BBLKBLKEF0 is suitable for a variety of applications including home automation, machine automation, lighting systems, access control, signalization, industrial control panels, control circuits, AC or DC motors and circuit breakers. PB1973BBLKBLKEF0 pushbutton switches are required in most panel assemblies where a system should be activated or deactivated by pushing a button. They are commonly used in machinery, HVAC (heating, ventilation and air conditioning) systems, process control systems and security systems.

PB1973BBLKBLKEF0 pushbutton switches are also suitable for use in food and beverage processing due to their dust-proof and water-resistant features. They are typically used for high-frequency switching, such as in a production system, where a large number of switches are operated frequently. Additionally, they are suitable for mounting in hazardous areas where flammable vapors or dusts are present.
