DPDT 15A 3 Position Switch
 Click to enlarge
|
All prices, including shipping, are in New Zealand Dollars (NZD) Up to 15A 250v AC.
This switch has 3 positions, up, down & a middle position. We love this type of switch, if you had to buy just one large switch for every project then this would be the one. It can be used as a simple on & off switch or used to control a motor forward & backward by reversing the polarity to the motor with the centre switch position turning the motor off. We controlled the electric motor on our fishing kontiki winch with this switch. Every switch will come with the securing nut & the on & off metal sign. DPDT means Double Pole Double Throw, double pole meaning the centre pins can connect with the left or right pins depending on the switch position. Double Throw means that it has 2 rows of pins, 3 on each side. A very versatile switch, or for something a little smaller try the switch below. |
