Pushbutton switches are used to control some machine or equipment, and U821MHZGE is one of them. This type of switch is widely used in industrial and commercial applications, such as starting and stopping machines, operating panels, controlling the flow of material, and more.

U821MHZGE pushbutton switch has a main contact, a releasing contact, a molded black plastic shell, and a capacitor. It is designed to be used in 110 V AC current. The contacts are non-shorting type.

The main contact is made of silver or gold contacts which are positioned by a blade that is attached to a cam. The cam is connected to the plunger of the switch. When the plunger is pushed down, the cam will rotate clockwise and the contact will make contact with the main contact. This completes the circuit and the switch will operate.

The releasing contact is also made of either silver or gold contacts. It is located on the other side of the blade and is also activated by the plunger. When the plunger is released, the cam will rotate counterclockwise and the contact will be opened. This will open the circuit and will stop the operation of the switch.

The molded black plastic shell is used to provide protection to the contacts and keep dirt, dust, and other contaminants out of the switch. It also helps to provide a secure place to mount the switch on the machine or equipment.

The capacitor is used to prevent any arcs from forming in the contacts when the switch is turned on. This helps to ensure that the contacts last longer and the switch operates more efficiently.

These pushbutton switches are generally very reliable, and are very easy to install. They can be used in a variety of applications and are generally very cost effective. They are also very durable, and can be used in a wide range of environmental conditions, such as extreme temperatures and wet or dry conditions.

U821MHZGE Pushbutton switches are ideal for controlling electrical devices and machines in industrial, commercial, and domestic applications. They are easy to operate and require minimal maintenance. They are also good for controlling the flow of material, applying or releasing pressure, and turning machines on or off. They are reliable, durable, and cost-effective, and they are an excellent choice for any application.
