A pushbutton switch is a type of electrical switch used for momentary or temporary control of an electrical circuit. The most common type is the single-pole, single-throw (SPST) pushbutton switch, which carries two terminals and is operated by pushing a button to make and break an electrical connection. Pushbutton switches are commonly found on fire alarms, circuit breakers and other machines that often require the operator to take action quickly and reliably.

PVA2 EE H3 pushbutton switches are a type of electrical switch designed to operate with an electrical current through an electromagnetic field. These pushbutton switches are often used to control remote control units, including those used in medical, industrial and commercial applications. The switch is activated when an electrical current passes through the switch, creating an electromagnetic field. When the field is strong enough, it generates an electrical current that causes the circuit to activate.

The PVA2 EE H3 pushbutton switch has a wide range of uses, and it can be used in a variety of applications. In the medical field, it can be used to control devices such as ventilators and patient monitors, as well as to control hospital beds. In the industrial field, the switch can be used for controlling machine or process automation, or for controlling switches or circuit breakers. It is also used in many commercial applications, such as door locks, security systems and vending machines. In addition, the switch can be used in motion control systems, such as garage door openers or motorized wheelchair systems.

The working principle of the PVA2 EE H3 pushbutton switch is based on the use of electromagnets. This switch has a set of two independent electric coils, one serving as the primary control coil and the other as the secondary control coil. The primary coil is connected to the main power supply, while the secondary coil is connected to the switch. When the switch is activated, it creates an electrical current that flows through the coils, creating a magnetic field. This magnetic field attracts a metal groove inside the switch, causing the switch to move and make contact with the electrical circuit, thereby closing the circuit.

PVA2 EE H3 pushbutton switches are easy to install and come in a variety of styles and sizes. They also have different operating characteristics, including: time delay, temperature limit, adjustable current limit, adjustable lockout time, and actuator type. These switches are suitable for use in a variety of industrial, commercial and residential applications. Their solid construction means that they are durable and reliable, and can withstand long-term wear and tear.
