PVA20AH12.2N

Pushbutton Switches are very important components in almost all kind of machines and devices in industry or home use. It can be used to control the power supply, change the direction of specific circuit, reset the timer, etc. In this paper, it is going to introduce PVA20AH12.2N, one of the push button switch, in detail.

PVA20AH12.2N is a poles and throws pushbutton switch which is being known as multipurpose because it can do many tasks. In most of the applications, it is used as an on/off (momentary) switch, but it is also suitable for momentary and maintained pushbutton switch applications. It is designed to make and break circuits when pushed and released providing energy saving features since it is energy efficient by design. The contact point can be aligned or switched out of the application directly.

It is a two-pole pushbutton switch which means it can control two circuits simultaneously. It has a U-shaped silver contact that conducts at lower current and is intuitively engaged and disengaged for reliable operation. In electrical power parts of machinery, there is also a quick disconnect feature to allow for quick engagement at either end of the pole. It can be used as a power supply switch in both circuit designs, so it can be used in a variety of ways depending on the application. The poles have a high conductivity spring formed from Brass allowing for maximum contact efficiency. Spring contact pressure is adjustable to fit different contact materials.

The poles can be locked in the OFF position with a collar for safety. With this feature it can be prevented from turning ON accidentally. It also complies with EMF/EMC/RFI standards that do not require a separate EMI shield. The switch comes with three choices of actuators, which include Momentary, Maintained and Miniature; each having an adjustable travel distance. Momentary switch is suitable for tasks such as resetting the timer, while Maintained switch can be used for controlling the power supply. The rating of the switch is 5 A at 125 V AC, 3 A at 250 V AC, and 3 A at 30 V DC.

PVA20AH12.2N switch is mostly used in household applications, but it can also be used in motors, relays, wiring systems, diesel locomotives, etc., because it has a low activation time. It has a mechanical life of over 200,000 operations, offering a longer service life. The terminals are insulated to guarantee safety. It has a compact size, which makes it ideal for limited space applications.

In conclusion, PVA20AH12.2N is a multipurpose switch which is designed to be robust and reliable. Its contact pressure is adjustable and the pole lock in the OFF position with a collar for safety. It is energy efficient and it can be used in a variety of applications such as household, motors and wiring systems, etc.
