Stainless Steel Illuminated Double Pole Changeover Switches I am connecting the positive from the battery to the B terminal, Horns connected to the H terminal (horns are grounded on the other end). To avoid wasting too many GPIOs on the Pi it pays off to purchase a GPIO port expander with more than 4 channels. $39.13. This will also be available from the manufacturer's data sheet, or may be printed on the case of larger relays. There's a problem loading this menu right now. Top Rated Seller Top Rated Seller. The circuit is based on a NE 555 and two transistors for driving the relay © 2020 Copyright Pickering Electronics Ltd, Stephenson Rd, Clacton, Essex, England, CO15 4NL. You can drive the relay primary from the 5 Volt source, while switching it using the 3.3 Volt signal, by using an N-MOSFET as a switch: The simulation link is here. Relays may have one or more poles, indicated in drawings by a single line switch connected to a pin of the relay. 3V 12V 18V 5A. Assess the contact configuration of the relay.
