B12JJHF

Toggle switches are one of the most common switches used for various purposes. The B12JJHF toggle switch is a kind of double pole single throw (DPST) toggle switch, which is mainly used as an On/Off function switch. This toggle switch is made of nickel-plated brass and its contact rating ranges from 0.5A at 125VAC and 0.3A at 250VAC. 

The main application of the B12JJHF toggle switch includes lighting control and home appliance control. It can be installed in places such as domestic electrical appliances and office equipment as an On/Off switch. The switch has two terminals, which offer polarity reversal. With its metallic contact mechanism, the switch ensures consistent switching performance. It is also easy to install with the help of a detent or cylindrical cam mechanism. 

The working principle of the B12JJHF toggle switch is relatively simple. When its toggle is in the up position, the switch is “on”. It connects two conductors together and the circuit is complete. When the toggle is in the down position, the switch is “off”. The toggle switch will open the circuit, disconnecting the two conductors, and the circuit is broken. Additionally, it has two terminals, which allow for polarity reversal. With the two terminals, the two poles of the switch can be connected differently.

Overall, the B12JJHF toggle switch is a low cost switch with a reliable performance. It is easy to install and its working principle is simple to understand. It is mainly used to control lighting and home appliances and its polarity is easily reversible with its two terminals. The B12JJHF toggle switch is a great choice for users who need an effective and economical way to switch device On/Off.
