Rocker switches are also known as boat switches because most of these switches are shaped like the arc of a boat. The wiring pins of the ship switch are divided into two terminals and three terminals. The following is a brief understanding of the main differences between the two and three pins of the ship switch:
1. 2PIN Rocker switch
The boat switch, like the usual switch, mainly plays the effect of opening and closing the circuit. Never allow his two terminals to connect a wrong positive and negative, that will cause a short circuit.
The correct connection is that the positive terminal of the power supply can enter either terminal of the ship switch, and then its other terminal leads to the access load and then returns to the negative terminal of the power supply.
2. 3PIN Rocker switch
The three terminals should not have an indicator light, but with a normally open and normally closed point, usually the center is the middle point, and the two ends are normally open or normally closed (i.e. the switch in different directions).
When making a transfer switch, the center is moving contact, the two ends are fixed contact; Do a single switch, can only be connected to the center column and the edge of any column.
Electrical components have their own life, boat switch is no exception. Before buying the ship switch, the service life of the ship switch should be taken into account. Generally, the life of the good ship switch is more than 500,000 times, and the poor is not necessarily.
